So, we know in the slope intercept formula (y=mx+b) we know that m=slope and b=y intercept. So for the equation I gave you m=1/4 and b=2. So, from the y-intercept (which is 2) you move 4 spaces to the right and 1 space up. Hope that helps!:) Comment ( 4 votes) Upvote Downvote Flag more Show more...
