PLEASE HELP! WILL MEDAL & FAN!

Which is an equation in point-slope form for the given point and slope?

Point: (8, -4) ; Slope: -5/6

A. y+4=-5/6(x+8)
B. y-4=-5/6(x+8)
C. y+4=-5/6(x-8)
D. y-4=5/6(x-8)

Answer 1

we will have to use the following form

y - y1 = m(x - x1)
m is the slope and we have the point (8,-4) where y1 is -4 and x1 is 8
So substitute in the original form

y - (-4) = -5/6 (x - 8)
simplify the left side
y + 4 = -5/6(x - 8)
