Answer:
The slope-intercept form is y=x-5
The graph is in the picture below
Step-by-step explanation:
To find the slope-intercept you need to move y all by itself:
y=mx+b
subtract 3x on both sides:
-3y=-3x+15
Divide by -3 on both sides:
y=x-5
Hope this helps!
(Why I took two pictures is because to show you that the line is the same even with it being slop-intercept form)
