The equation of a line is 5x + 10y = 15. Which if the following points lines on the line? (–3, 0) (–1, 2) (1, –2) (0, 3)
divide both sides of the equation by 5 and you get: x+2y=3 so using the points in order... -3+0=3 false -1+4=3 true 1-4=3 false 0+6=3 false So the only point that lies upon the line given is (-1,2)
(-1,2) You have to convert it into y = mx + b then you just graph that and see which points match up.
