The slope formula is delta y/delta x=m You can choose any two points. Let's choose (0,25) and (1,30) 30-25/1-0=5/1=5 Slope intercept form is y=mx+b b=the y intercept y=5x+25 since (0,25) is the coordinates for the y inthercept. Plug in 200: y=5(200)+25 Simplify and you get that y=1025 Your answer is 1025 Your welcome
