4x-3y=-9
The first step is to isolate your y value.
Subtract 4x from both sides to get
-3y=-4x-9
Then, divide your whole equation by -3. This gives you y=4/3+3
To graph, plot (0, 3), or three on your y-axis to get your y-intercept.
For your slope, use the rise/run (go up 4, across 3)
You should have a positive slope.
I believe the answer is n= -2
250m should be the answer
5x+3=6x-4
-x=-7
X=7
Hope this helps!
You would have to use the quadratic formula because it’s not a perfect square
