Answer
y=0x+7
Explanation:
Parallel lines share the same slope, to solve, you need to find the slope of the line it is parallel to.
3-5y=15, since this equation has no x value, that basically means that the slope is 0.
Since the slope is 0 and you have an ordered pair, you can now substitute the ordered pair and the slope into slope intercept form to solve for 'b' or the y intercept.
y=mx+b
(-5,7)
7=0(-5)+b
b=7
y=0x+7
