Answer:
slope of y = -5.5 is 0.
Slope of 4x - 4y = 22 is 1
Explanation:
y = -5.5 is a horizontal line going through -5.5. The slope does not go up or down so we say that the slope is zero.
4x - 4y = 22 Subtract 4x from both sides
4x - 4x - 4y = -4x + 22
-4y = -4x + 22 Divide all the way through by -4
=
+
y = x -
The sloe is the number before the x. If we do not see a number, we assume it is 1.
