in slope-intercept form (y=mx+b), plug in your known values of y, x, and m. Solve for b. YOu get the equation.
OpenStudy (anonymous):
Use the form y = mx + b
m = slope
b = y-intercept
Plug in what you have.
y = 7/8x + b
Plug in the coordinate on the line.
-8 = 7/8(6) + b
-8 = 21/4 + b
-53/4 = b
y = 7/8x - 53/4

can you simplify your answer

What do you mean?
OpenStudy (anonymous):
my fault numbers should have read m=3/4x,(6,-8)

Do the same thing.
y = 3/4x + b
-8 = 3/4(6) + b
-8 = 9/2 + b
-25/2 = b
y = 3/4x - 25/2
