A line has a slope of 2 and passes through the point (4, 0). What are the coordinates of another point that is on the line? (Points : 1)
(2, 0)
(0, 2)
(4, 6)
(6, 4)

yes.... slope=(y-y1)/(x-x1)=(-5-(-1))/(2-(-1))=(-5+1)/(2+1)=-4/3

y-(0)=2(x-(4)
y=2x-8
D is the answer if you put x=6 in the above eq you will get 4
