Question

Which equation represents the line that passes through points (1, -5) and (3,-17)

A)y=-6x+1
B) y = 6x+1
C)y=-6x-1
D)y=6x-1

Answer 1

A) y=-6x+1

Explanation:

m=(y2-y1)/(x2-x1)

m=(-17-(-5))/(3-1)

m=(-17+5)/2

m=-12/2

m=-6

y-y1=m(x-x1)

y-(-5)=-6(x-1)

y+5=-6(x-1)

y=-6x+6-5

y=-6x+1
