y+9=2x+3

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Move all terms not containing y to the right side of the equation.

Subtract 9 from both sides of the equation.

y=2x+3-9

Subtract 9 from 3.

y=2x-6

y=2x-6

y=2x-6

Using the slope-intercept form, the slope is 2.

m=2
