Answer:
5y + 15x = 25, 9x - y = -4
Step-by-step explanation:
The standard form is Ax + By = C. We can make this simple by first creating the slope intercept equations of both questions:
1. y = (-3/5)x + 5
2. y = 9x + 4
For the first one, we must first get rid of the denominator by multiplying everything by 5, so we get 5y = -15x + 25, and then you can add 3x to both sides to arrive at your first standard eqn, 5y + 15x = 25.
For the second, all you need to do is swap the y and the 4, subtracting both y and 4 from each side, arriving at 9x - y = -4
