Question

What is the slope that passes through the pair of points? (-1, 4), (3, 12)
A. -2
B. 2
C. 4
D. -4

Answer 1

Use the formula (since I can’t put special characters) y sub 2 minus y sub 1 divided by x sub 2 minus x sub 1 and plug the coordinates into this equation

Answer 2

Answer:
slope = 2

Explanation:
The slope of the line can be calculated using the following rule:
slope = $\frac{y2 - y1}{x2 - x1}$

In the given, we have:
point (-1 , 4) representing (x1 , y1)
point (3 , 12) representing (x2 , y2)

Substitute with the givens in the above formula to get the slope as follows:
slope = $\frac{12 - 4}{3 - -1} = 2$

Hope this helps :)
