y=-74x-3

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 74.

y=-x⋅74-3

Move 7 to the left of x.

y=-7×4-3

y=-7×4-3

Rewrite in slope-intercept form.

y=-74x-3

y=-74x-3

Using the slope-intercept form, the y-intercept is -3.

b=-3

Find the Y-Intercept y=-7/4x-3
