Answer:
y=2/3x-3
Step-by-step explanation:
The slope-intercept formula for a line is: y=mx+b.
If the y-intercept is (0, -3), that means that the y-intercept ("b") is -3.
Updated equation: y=mx-3.
Plug in the point that you were given.. (-9,-9).
-9=-9m-3.
Add 3 to both sides.
-6=-9m.
Divide by -9.
m=-6/-9 = 6/9 = 2/3
The slope ("m") equals 2/3.
y=2/3x-3 is your equation.
