First you have to put it in y=mx+b form
Then, just plug those two numbers in.... y=-3 x=2 m(slope)=-5 b(y-intercept)=-8
-3 = -5(2) + -8 now simplify :D
^ ^
-3= -10 - 8
is that true or not? lets see
-10-8= -18
-18 is not equal to -3 so, no, it does not pass through the point (2,-3) hope this helped :D
