What is the slope of the line that passes through (2, 12) and (4, 20) ?

 4

Step-by-step explanation:

The slope of a line passing through two points (a,b) and (c,d) is given by :-

The given points : (2, 12) and (4, 20)

Then , the slope of a line passing through two points (2, 12) and (4, 20) is given by :-

Hence, the slope of the line through the points  (2, 12) and (4, 20) = 4
