E4. In the standard coordinate plane what is the distance between (-5, 2) and (1, -6)? If you do not like the distance formula you can use the Pythagorean Theorem

E /3 = ?  A. -18  B.  C. 9  D.  E.

E6. The parabola below is a graph of which equation? (-2, 4) (-4, 0) (0, 0)  A. y = (x - 2)  B. y = (x + 2)  C. y = -(x - 2)  D. y = -(x + 2)  E. y = x 2 + 4x + 8

Plug (-2, 4) into choice C y = -(x - 2) = -(-2 - 2) = -(-4) = = -12 False E6. The parabola below is a graph of which equation? (-2, 4) (-4, 0) (0, 0) Because the parabola points down we know that the x 2 term will be negative. (Negative Frown Face)  C. y = -(x - 2)  D. y = -(x + 2) Plug (-2, 4) into choice D y = -(x + 2) = -(-2 + 2) = -(0) = = 4 True
