The slope of this line is 1

The y-intercept is 10 so the slope intercept equation of this line is

- y = mx + b
- y = 1x + 10

The slope of this line is 1/3

The y-intercept is 20 so the slope intercept equation of this line is

- y = mx + b
- y = 1/3x + 20

The slope of this line is 2

The y-intercept is 0 so the slope intercept equation of this line is

- y = mx +b
- y = 2x

The slope of this line is 2

The y-intercept is 0 so the slope intercept equation of this line is

- y = mx +b
- y = 2x
