Question

the line passing through (9,y) and (3,0) is parallel to the joining (3,4) and (-1,2). find y? i got 3 is this correct?

Answer 1

Slope of line passing through (3, 4) and (-1, 2)
m = (2 - 4)/(-1 - 3) = -2/-4 = 1/2

Slope of line passing through (9, y) and (3, 0)
m = (y - 0)/(9 - 3) = 1/2
y/6 = 1/2
y = 3

You are correct.

Answer 2

thanks :)
