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:
slope = 2

Step-by-step explanation:
The slope of the line can be calculated using the following rule:
slope =
(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 =
(12 - 4)/(3 - -1) = 2

Hope this helps :)
