3×-3y=6

The y intercept would be -2 and the slope is 1. The formula is y=mx+b. So you would subtract 3x to the other side. Then you would divide -3 from y to both -3x and 6. Your y=mx+b would be y=x-2

The slope of this line is 1 and the y-intercept is -2.

In order to find this, you need to put it in slope intercept form. This is done below for you.

3x - 3y = 6 -----> Subtract 3x from both sides

-3y = -3x + 6 -----> Divide by -3

y = x - 2

Now that you have this, you can find the slope by looking for the coefficient of x. In this case it is 1. You can find the intercept as the constant at the end, which is -2.
