Answer:
9x + 5y = -15
Explanation:
Standard form is Ax + By = C, where A, B, and C are integers and x and y are variables. We need to rearrange the given equation to match this formula.
y = -
x - 3
Multiply both sides by 5 to get rid of the fraction
5y = -9x - 15
Add 9x to both sides to put it in standard form
9x + 5y = -15
