y=-47x+9

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 47.

y=-x⋅47+9

Move 4 to the left of x.

y=-4×7+9

y=-4×7+9

Rewrite in slope-intercept form.

y=-47x+9

y=-47x+9

Using the slope-intercept form, the slope is -47.

m=-47
