Answer:
[tex]y=\frac{3}{4}x-9[/tex]
Step-by-step explanation:
We are using the general equation of a straight line, which is
y=mx+b, where y&x are the coordinates, m is the slope and b is the y intercept. We are trying to solve for b, so we can plug in these values that we know into the formula in order to find b:
[tex]-3=\frac{3}{4}(8)+b\\-3=6+b\\-3-6=b\\b=-9\\\\y=\frac{3}{4}x-9[/tex]
