Does (0,2) make the equation y=x^{2}-3x+2 true? In the ordered pair (0,2), 0 is the x-value and 2 is the y-value. Plug x=0 and y=2 into the equation.

Yes, 2=2. So, the point (0,2) satisfies the equation y=x^{2}-3x+2

Does (0,-1) make the equation y=x^{2}-3x true? In the ordered pair (0,-1), 0 is the x-value and -1 is the y-value. Plug x=0 and y=-1 into the equation.

No, So, the point (0,-1) does not satisfy the equation y=x^{2}-3x
