 Question 636044: I need assistance with writing point-slope form for an equation with the slope and one point already given. one example is "what is the point-slope form of a line through (4,-4) with a slope of -9/4?" I don't even know how to begin solving this problem. I practically need a lesson on how to do this kind of thing in general.Answer by ewatrrr(10682)   (Show Source): You can put this solution on YOUR website! ``` Hi, Using the standard slope-intercept form for an equation of a line y = mx + b where m is the slope and b the y-intercept. line through (4,-4) with a slope m = -9/4 |Using ordered pair (x,y): (4,-4) to solve for b 5 = b y = (-9/4)x + 5 (Note: line slants to the left (back 4 Up 9) from point(4,-4) using point-slope form as the directions state || which also says: y = (-9/4)x + 5) ```
