Answer:
Your answer is y = 5/4x + 2.5. When you're writing out the fraction 5/4 write it out the traditional way with the 5 on top and the 4 on the bottom. Also, DON'T put the x right next to the 4 like I have, write it to the side of the entire fraction, otherwise you'll get a completely different line. The only reason I've written it out like that is because it's the only way a fraction can be typed on a keyboard. Hope all that makes sense.
