Hey!
------------------------------------------------
Steps To Solve:
x - 5y = −15 solve for y
~Isolate y by subtracting x to both sides
x - 5y - x = -15 - x
~Simplify
5y = -15 - x
~Divide 5 to each side
5y/5 = -15/5 - x/5
~Simplify
y = -3 - 1/5x
~Put into slope-intercept form
y = -1/5x + 3
------------------------------------------------
Hence, the answer is 
------------------------------------------------
