Chapter 5 STUDY GUIDE

Remember:

Find the slope of the line passing through each pair of points.

1.) (-3, 2) , (3, -8)

2.) (-1,5) , (-6, 5)

3.) (4, 0) (4, 5)

4.) (1, -4) (-2, -5)

Assume y varies directly as x.

1. Write a direct variation equation that relates x and y.

2. Solve for the missing variable.

5.) If y = 5, when x = 10, find y when x = -15.

Remember:

The constant of

variation is k.

and

6.) If y = -9 when x = 3, find x when y = -8.

Set up a proportion

and cross multiply to

solve for the missing

variable!

7.) If y=3 when x =2, what is the constant of variation?

8.) If y=-4 when x=-12 what is the constant of variation?

Write an equation of the line with the given slope and y-intercept.

Remember:

9.) slope = , y-intercept =

10.) slope =
