y = x + 2 y = -x + 4 x + 2 = -x + 4 2x + 2 = 4 2x = 2 x = 1 y = x + 2 y = 1 + 2 y = 3 (1, 3)
2(x - 2)(x + 4) = 0 x = 2, -4
y equals x-4 plus 2 is the same as y = x-2. You just translate the graph of y=x, 2 units to the right, OR 2 down.
That factors to (x - 2)(x + 4) x = 2, -4
4
x = -2
-2
2 x 2 = 4 x 60 = 240
x = -2
4
4
-(2)Squared = 4
-x -2 = 2 so -x = 2+2 = 4 and so x = -4
4 + x = 2x --> 4 = 2x - x --> 4 = x: x = 4
No, it is not.
