Question

What is the slope of the line that passes through the points (1,7) and (-4,-8)?

A) -3
B) -1/3
C) 1/3
D) 3

Answer 1

D. 3

Explanation:

To find the slope of a line, we can use the equation y2-y1/x2-x1=m or slope.

All we can do now is insert the values of the points into the equation.

-8-7/-4-1=m

-15/-5=m

3=m

Thus, the slope is 3.

Hope this helps!

Answer 2

D) 3

Explanation:

Given: The line passes through the points (1, 7) and (-4, -8)

Here we have to use formula to find the slope.

Slope (m) = (y2 - y1)/(x2 - x1)

Here x1 = 1, y1 = 7, x2 = -4 and y2 = -8

Now plug in these values in the above formula, we get

slope = (-8 - 7) / (-4 - 1)

= -15/-5

slope (m) = 3

Therefore, the slope of the line is 3.

Answer: D) 3

Hope you will understand the concept.
