Okay theres another part to this equation and I'm not sure if this is the right answer either.

5x+6y=18 solve for y.

6y = 18-5x
y = (18-5x)/6

The second part is when graphed this equation would be a line. What is the slope and y-intercept of this line?

The slope would be 3
y-intecept is (-5/6)

Is the slope and y-intercept right?

I got it, I have it backwards the slope is (-5/6) and the y-intercept is 3
