Question

What do I do when you have a question like "y-1=4/5(x+15)" I have no idea what to do next!

Answer 1

`y - 1 = (4)/(5(x + 15))`


`y - 1 = (4)/(5(x) + 5(15))`


`y - 1 = (4)/(5x + 75)`


`y - 1 = 0.8x - 0.053`


`y - 1 + 1 = 0.8x - 0.053 + 1`


`y = 0.8x + 0.947`

Answer 2

distribute the 4/5 to the x and 15 so you should have y-1=4/5x+12
next you must get y alone so add one to both sides of the equation
the final product is y=4/5x+13
