Question

slope 3/4, y intercept: 9
write an equation of the line with the given slope and y-intercept

Answer 1

if anyone wouldn't mind helping me out.

Answer 2

Y intercept is when X = 0. It's another way of saying one of the points on the line is (0,9).
m (slope) = (3/4)

Slope intercept form is:
y=mX+b, where m = slope

First, solve for the Y intercept (which will get you b):
9 = m(0)+b

Then substitute b and m into y=mx+b.
