y=-83x+56

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 83.

y=-x⋅83+56

Move 8 to the left of x.

y=-8×3+56

y=-8×3+56

Rewrite in slope-intercept form.

y=-83x+56

y=-83x+56

Using the slope-intercept form, the y-intercept is 56.

b=56

Find the Y-Intercept y=-8/3x+5/6
