Question

Write an equation in point-slope form for the line through the given point with the given slope. (-7, 9); m=4/5

y+7=4/5(x-9)
y-7=4/5(x+9)
y-9=4/5(x+7)
y+9=4/5(x-7)

Answer 1

OK, you are given a point and the slope so all you need to do is plug that into the following equation: y-y1=m(x-x1) and solve

Answer 2

where m = given slope

Answer 3

yeah, but i dont know how lol. just helping a friend, i have no clue how to do this stuff XD
