Question

Find the slope of the line.
A coordinate grid is shown with the x-axis between negative 4 and 4 with interval marks representing one unit, and the y-axis between negative 3 and 5 with interval marks representing one unit. A line is drawn connecting the points left-parenthesis 1 comma negative 2 right-parenthesis and left-parenthesis 3 comma 2 right-parenthesis.
A. –2
B. 2
C. –one-half
D. one-half

Answer 1

We can use the slope formula, which is:

slope = (change in y)/(change in x)

To find the change in y, we subtract the y-coordinate of the first point from the y-coordinate of the second point:

2 - (-2) = 4

To find the change in x, we subtract the x-coordinate of the first point from the x-coordinate of the second point:

3 - 1 = 2

Therefore, the slope is:

slope = 4/2 = 2

The answer is (B).
