Question

What is the slope of the line?

Answer 1

The formula of a slope:

`m=(\Delta y)/(\Delta x)`

Δy = 2

Δx = 1

Substitute:

`m=(2)/(1)=2`

Answer: 2

Other method.

The formula of a slope:

`m=(y_2-y_1)/(x_2-x_1)`

Find two points.

(0, 1) and (1, 3). Substitute:

`m=(3-1)/(1-0)=(2)/(1)=2`

Answer: 2
