Question

name a point that lies on the line 3x+8y=-7

Answer 1

If you let x = 0, you get 8y = -7

So y = -7/8 giving you your Y value and you already have your x which is 0.

Final answer = (0,-7/8)

Answer 2

Oh and I forgot to mention, to check if that is right just type it into your calculator and you will get -7 from
(3x0) + (8*-7/8)
