Question

Recall that the absolute value $|a|$ of a number is its distance from zero. For example, $|-3| = 3$ and $|9-7| = |7-9| = 2$.

Enter the letters of the points that are on the graph of $|x| = |y|$.

Answer 1

Answer: H, F, A, E

Explanation:

Since we know that |x|=|y|, the coordinates have to be the same (ex. 8,8).

Also, we know that |-a|=|a| and |a|=|a|, so using this, we can look at the graph and determine which coordinates follow these.

A = 3,3 F = -2,-2 (becomes 2,2) E = 6,6 H = 6, -6 (becomes 6,6)
