Answer:
Step-by-step explanation:
Substitution method = plug in the slope and the (x, y) point values into y = mx + b, then solve for b. ...

Step-by-step explanation:
The answer would be A: (x-3)(x-3)
Explanation: (X-3)(X-3) would create three new numbers: x^2, -6x, and 9,
(-6x is created because x*-3 + x*-3 = -3x + -3x, or -6x)
9, as you know, is 3*3 or -3*-3
