Hi bobbyboy1111

From the equation : (-1) = (-1)(-6) + b, yes the value of b is (-7). But I don't know what y = -1x + -7 is.

It's true that y = -1x + -7 = - x - 7 is linear equation, but I don't know if your answer is right or wrong. Maybe you can post the whole question ?

Btw, (+ -7) is very ugly notation....
