Question

Reflection over the line y= x of the point (-7, 4). Please assist with this math problem.

Answer 1

ANSWER:

$P^{\prime}(4,-7)$

STEP-BY-STEP EXPLANATION:

We have to rule for reflection about the line y = x is:

$P(x,y)\rightarrow P^{\prime}(y,x)$

Therefore:

$P(-7,4)\rightarrow P^{\prime}(4,-7)$
