Question

A linear relationship is given in the table.

x y
4 11
2 7
0 3
−2 −1
What is the slope of the relationship?
(A)−3
(B)−2
(C)2
(D)3

Answer 1

C

Explanation:

slope = diff in Y / diff in X

-4/-2 = 2

Answer 2

Answer: The answer is C

Explanation:

First you need to calculate the difference between the data for x and the data for y. Lets start with the x axis.

X axis:

4 - 2 = 2

This means the the difference between each x point is -2.

Now for the y axis.

Y axis:
11 - 7 = 4

7 - 3 = 4

This means the the difference between the y axis points is -4

Now use rise over run to find the slope.

The rise is always the y coordinates and the run is always the x coordinates

So divide the difference of y by the difference of x.

-4/-2 = 2

The answer is C.
