Finding the y-intercept of?

Question

I simply forgot how to do this
5x-5y=30

Answer 1

Given line equation is 5x-5y = 30

Apply subtraction property,subtract 5x from each side.

5x-5y-5x = 30-5x

-5y = 30-5x

Apply division property,divide by negitive 5 to each side.

-5y/-5 = (30-5x)/-5

y = -6+x

y = x+(-6)

Slope y intercept form is y = mx+b

Slope m = 1, y intercept = -6
