has been used for x hours.

When graphed, all of these points lie on the same line.

What is the y-intercept and slope of this line?

Drag an answer into each box.

Answer 1

yint -= (0,100) slope = -5 2/3

Explanation:

yint is (0,100) because thats where it hits the y axis

slope equation is (y1-y2)/(x1-x2), just pick out any two points to do this with

(83-66)/(3-6)

17/-3

-5 2/3

Answer 2

slope -17/3 y -intercept 100
