Question

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

Answer 1

20 - 12/ 4 - 2 = 8/2 = 4. slope is 4

Answer 2

Answer:  4

Step-by-step explanation:

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

$m=\dfrac{d-b}{c-a}$

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 :-

$m=\dfrac{20-12}{4-2}\\\\\Rightarrow\m=4$

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