Rewrite in slope-intercept form.
The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
Move all terms not containing y to the right side of the equation.
Subtract 9 from both sides of the equation.
Subtract 9 from 3.
Using the slope-intercept form, the slope is 2.
Find the Slope y+9=2x+3
