Hello, mr.confusied!

y = -(2/3)x + 7
when graph does it increase or decrease from left to right

Plug in some values of x . . . from left to right:

At x = 0: . y .= .-(2/3)(0) + 7 .= .0 + 7 .= .7

At x = 3: . y .= .-(2/3)(3) + 7 .= -2 + 7 .= .5

At x = 6: . y .= .-(2/3)(6) + 7 .= -4 + 7 .= .3

It looks like it's decreasing, doesn't it?
