Choose the point-slope form of the equation below that represents the line that passes through the points (-6, 4) and (2, 0).

y - 4 = - (x + 6)
y - 4 = 2(x + 6)
y + 6 = - (x - 4)
y + 6 = 2(x - 4)

And how did you get the answer

Respuesta :

apologiabiology
point slope form
y-y1=m(x-x1)
slope=m
a point is (x1,y1)

slope=(y2-y1)/(x2-x1)
given
(-6,4) and (2,0)
slope=(0-4)/(2-(-6))=-4/(2+6)=-4/8=-1/2

a point is (-6,4)
x1=-6
y1=4

y-4=-1/2(x+6)
