Best ResponseYou've already chosen the best response.0The pointslope form expresses the fact that the difference in the y coordinate between two points on a line (that is, y − y1) is proportional to the difference in the x coordinate (that is, x − x1). The proportionality constant is m (the slope of the line).

Best ResponseYou've already chosen the best response.0it's y  y1 = m(x  x1) idk if that's what you meant...

Best ResponseYou've already chosen the best response.0so it should be easy. you're just substituting the y in the coordinate for y1, the x in the coordinate for x1, and 4 for m

Best ResponseYou've already chosen the best response.0so the answer is y  y1 = m(x  x1)

Best ResponseYou've already chosen the best response.0no, you didn't substitute

Best ResponseYou've already chosen the best response.0our point is (4,1) so x1 is 4 and y1 is 1

Best ResponseYou've already chosen the best response.0y  y1 = m(x  x1) y – 1 = (4)(x – 4) y  1 = 4(x  4) y  1 = 4x + 16 y = 4x + 16 + 1 y = 4x + 17

Best ResponseYou've already chosen the best response.0STEp by STEp y  y1 = m(x  x1) y – 1 = (4)(x – 4) y  1 = 4(x  4) y  1 = 4x + 16 y = 4x + 16 + 1 y = 4x + 17

Best ResponseYou've already chosen the best response.0i thought the answer was supposed to be in pointslope form

Best ResponseYou've already chosen the best response.0so how can i write y = 4x + 17 to pointslope form

Best ResponseYou've already chosen the best response.0lol. it was already in pointslope in step 1. y  1 = 4(x  4)
