Answer:

For the first one the slope is 4

For the second one the slope is 0

Explanation:

Subtract 4x from both sides of the equation

-y=6-4x

Multiply each step in -y=6-4x by -1

y=-6+4x

For slope intercept form y=mx+b or y=4x+6

Slope : 4

Y intercept is (0,6)

To find the x intercept substitute in 0 for y and solve for x. To find the y intercept substitute in 0 for x and solve for y

X intercept: (9/5, 0)

Y intercept: (0,-9)

Slope is 0 using the formula y=mx+b
