Question 161944: Find the slope and y-intercept of -9x + 6y = 54
Here is what I did:
-9x + 6y = 54
+9x +9x
--------------
6y = 9x + 54
6y/6 (6y over 6) = 9x/6 (9x over 6) + 54/6 (54 over 6)
y = 9/6 (9 over 6) + 9
Simplified : y = 3/2x (3 over 2) + 9
So the answer I came up with is 9 is the slope, and the y-intercept is 3/2 (3 over 2).
Correct??

You did the work right, but got the labels wrong.
The slope is 3/2, the y-intercept is 9.

You work is perfect, but your conclusion is backwards. The slope is m=3%2F2 and the y-intercept is (0,9)

Remember, for any slope-intercept equation y=mx%2Bb the slope is "m" and the y-intercept is (0,b)
