x-3y=9

OpenStudy (mathstudent55):

What are you asked to do?

OpenStudy (anonymous):

It says graph each equation using the slope and y-intercept

OpenStudy (mathstudent55):

Ok, then first we nned to write it in the slope-intercept form. To do that, solve the equation for y.

OpenStudy (anonymous):

that doesn't work julianchico and I don't know how to solve for y :(

OpenStudy (anonymous):

Do I add 3y to each side or something

OpenStudy (mathstudent55):

Since -3y is on the left side, I suggest you leave it there and instead, subtract x from both sides.

OpenStudy (anonymous):

Hey again, you want y to be alone, so start by getting rid of the x that is on the same side as y

OpenStudy (anonymous):

x-3y=9 -x -x ------------ -3y= 9x?

OpenStudy (anonymous):

Close: x-3y=9 -x -x ------- -3y=9-x

OpenStudy (anonymous):

You want to get y completely alone, so how can you get rid of the coefficient -3?
