Equations of lines come in several different forms. Two of those are:

Solve Find the slope. Check Check your result by using the coordinates of the other point. You can use a linear equation to make predictions about values that are beyond the range of the data.

This process is called linear extrapolation. Problem-SolvingTip Determine Reasonable Answers Deciding whether an answer is reasonable is useful when an exact answer is not neccessary.

Write an equation of the line that passes through the given point and has the given slope. Write an equation in slope-intercept form to find the total cost C for p people. How much would it cost for 15 people? He starts the timer when the car is 5 feet away. After 2 seconds the car is 35 feet away.
