1. (-1) = (-1)(-6) + b
(-1) = (6) + b
(-7) = b
y = -1x + -7
???
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....
