Question

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

Answer 1

m = 3

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

Answer 2

Answer: 3

Explanation:

The formula for calculating slope is given as :

m =
`(y_(2)-y_(1))/(x_(2)-x_(1))`

`x_(1)=0`

`x_(2) = 2`

`y_(1) = -2`

`y_(2) = 4`

substituting into the formula , we have :

`m = (4-(-2))/(2-0)`

`m = (4+2)/(2)`

`m = (6)/(2)`

`m = 3`

Therefore : slope = 3
