Which the the complying with lines is perpendicular to the line ?    Explanation:

Perpendicular present will have actually slopes that are an unfavorable reciprocals that one another. Our an initial step will be to find the slope of the given line by placing the equation right into slope-intercept form.

You are watching: If two lines are perpendicular, then they form  The steep of this line is . The an adverse reciprocal will certainly be , which will be the slope of the perpendicular line.

Now we need to find the answer selection with this slope by convert to slope-intercept form.    This equation has actually a slope of , and must be our answer.

Explanation:

When identify if a two lines are perpindicular, us are just concerned about their slopes. Take into consideration the an easy equation of a line, , wherein m is the steep of the line. 2 lines space perpindicular come each various other if one slope is the an adverse and mutual of the other.

The an initial step that this difficulty is to acquire it into the form, , i beg your pardon is . Now we understand that the slope, m, is . The mutual of that is , and the an unfavorable of the is . Therefore, any kind of line that has actually a slope of will be perpindicular come the original line.

### Example inquiry #25 : Perpendicular currently

Which that the following lines is perpendicular to the line v the given equation: ? Explanation:

First we have to recognize that the equation is given in slope-intercept form, where is the slope of the line.

Two lines are perpendicular if and also only if the product of their slopes is . In other words, the steep of a line that is perpendicular to a provided line is the an adverse reciprocal of the slope.

Thus, because that a line with a offered slope that 3, the heat perpendicular to that slope must be the an unfavorable reciprocal of 3, or .

To twin check that that go indeed give a product of when multiplied by three merely compute the product: Report one Error

### Example question #26 : Perpendicular present

Are the adhering to two currently parallel, perpendicular, or neither:

and

They space neither perpendicular or parallel.

They space parallel.

They space perpendicular.

They are both perpendicular and parallel.

They space perpendicular.

Explanation:

Perpendicular lines have slopes whose product is .

The steep is regulated by the coefficient, from the genral kind of the slope-intercept equation: Thus the two lines room perpendicular because:

has and

has which as soon as multiplied together results in, .

### Example concern #27 : Perpendicular lines

Are the following two lines perpendicular:  Explanation:

For two lines to be perpendicular, their slopes have to have a product of . Uncover the slopes by the coefficient in prior of the . and so the two lines room perpendicular. The y-intercept does not matter for identify perpendicularity.

### Example inquiry #28 : Perpendicular present

Are the lines explained by the equations and perpendicular to one another? Why or why not?

Yes, because the product of their slopes is .

No, since the product of your slopes is .

Yes, due to the fact that the product of your slopes is not .

No, due to the fact that the product of your slopes is not .

No, due to the fact that the product of your slopes is no .

Explanation:

If the slopes of 2 lines can be calculated, an easy way to identify whether they space perpendicular is to multiply their slopes. If the product of the slopes is , climate the lines are perpendicular.

In this case, the steep of the line is and the steep of the line is .

Since , the slopes are not perpendicular.

### Example concern #1 : how To uncover Out If Lines are Perpendicular

Line , which adheres to the equation , intersects line at . If line also passes through , are and perpendicular?

No, since the product of your slope is not .

Yes, since the product of your slopes is not .

No, because the product of their slopes is Yes, due to the fact that the product of your slopes is .

Yes, because the product of their slopes is .

Explanation:

The product of perpendicular slopes is always . Understanding this, and also seeing the the slope of line is , us know any type of perpendicular line will have actually a slope of .

Since line passes through and , we deserve to use the slope equation: Since the two slopes" product is , the lines room perpendicular.

### Example question #2 : how To discover Out If Lines room Perpendicular

Are the complying with two present perpendicular: and  Explanation:

For two lines to be perpendicular they have to have slopes the multiply to get . The steep is found from the in the basic equation: .

For the an initial line, and because that the second  and so the lines are not perpendicular.

Report an Error

### Example question #1 : how To find Out If Lines are Perpendicular

Which that the adhering to equations to represent a line that is perpendicular to the line through points and ? Explanation:

If lines space perpendicular, then their slopes will certainly be an adverse reciprocals.

First, we need to find the slope of the given line.
