y=-45x-4

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Simplify each term.

Combine x and 45.

y=-x⋅45-4

Move 4 to the left of x.

y=-4×5-4

y=-4×5-4

Rewrite in slope-intercept form.

y=-45x-4

y=-45x-4

Using the slope-intercept form, the slope is -45.

m=-45

Find the Slope y=-4/5x-4
