Question

Calculate the slope of a line that passes through the points (6, -12) and (15, -3).

Answer 1

The answer is 1
rate of change is 9
(6 + 9 is 15 and -12 + 9 is -3)
constant rate of change = 9/9
= 1

Answer 2

Answer:

B. 1

Step-by-step explanation:

The slope is calculated by taking the difference in the y-coordinates of two points and dividing that by the difference in the x-coordinates of those two points.

Here, we have (6, -12) and (15, -3).

The difference in the y-coordinates is:

15 - 6 = 9

The difference in the x-coordinates is:

-3 - (-12) = -3 + 12 = 9

Divide 9 by 9:

9/9 = 1

The slope is thus 1, and the answer is B.
