Question

Find the slope of the line represented by the table of values.

A) −4
B) −1/4

C) 4
D) 1/4

Answer 1

B. -1/4

Explanation:

To get the slope you have to use the formula: y2-y1/x2-x1

y2-y1/x2-x1 = 4.47-5/-1-(-2)

4.75-5 = -.25

-1 - (-2) = 1

-.25/1 = -.25 or -1/4

Answer 2

B) −1/4

Explanation:

The slope represents the change in y values divided by the change in x values. We can use the formula

slope = (y2-y1)/(x2-x1)

(2,4) (-2,5)

slope = (5-4)/(-2-2)

= 1/-4

slope = -1/4
