You are watching: How can you use an equation to make a prediction from a pattern
5. An example would be x+4 = 86. Using equations, you will are able to predict data from a specific value of independent variable. You can see how does the independent variable affect the dependent variable. 7. The y is the cost of the pizza when you buy x slices at 1.50 per slice. So the equation in y = mx + b form is y = 1.5x
5. An open equation is an equation with one or more variables that may be true or false depending on the values of the variables. An example of and open equation is
- Notice that if
As you can see, when
- Let"s check what happen if
Since 15 is not equal to seven, when
6. Equations can be used as models to represent how a particular part of the real world works. Since model equations use variables to relate real world quantities, you can use equations to make predictions. For instance, suppose you have the equation
You can predict, using the equation, how much we are going to pay for 2 hours of parking.

Using an equation, we predicted that parking 2 hours will cost $1.
Notice that we can predict how much is going to cost a pizza of 8 slices just by replacing
