What is the slope of the line?
A) -3
B) -1/3
C) 1/3
D) 3

m = 3

Step-by-step explanation:

We are given 3 points on the line.

to find the slope, we just need 2 points, so we'll pick (1,1) and (2,4)

(refer to attached)

in our case, x₁=1     y₁=1    x₂=2   y₂=4

m = (4-1) / (2-1)

m = 3/1

m = 3

3

Step-by-step explanation:

The formula for calculating slope is given as :

m =

substituting into the formula , we have :

Therefore : slope = 3
