graph line, plot point. point on line? plug (x,y) into (x,y) of equation. does left hand side = right hand side? 4(1/2) - 3(-4) = -10, for instance will -10= -10?
OpenStudy (anonymous):
So is it a solution?
OpenStudy (anonymous):
No, 4(1/2) - 3(-4) = 2+12 = 14. 14 is not -1, so (1/2, -4) is not a solution.
OpenStudy (anonymous):
is not -10*
