A and B are on the line 3x+2y=6. At A x=0, what is y? At B y=0, what is x?

To find the y value at A, we know that x is equal to zero. This can be put into the equation of the line so that 3(0)+2y=6. Therefore 2y=6, and to get the y value, we divide each side by 2, giving us y=3 at point A.
To find the x value at B, we know that y is equal to zero. This can be put into the equation of the line so that 3x+2(0)=6. Therefore 3x=6, and to get the x value, we divide each side by 3, giving us x=2 at point B.
