Question

1. reflect triangle abc with a(3, -1), b(1, -5), and c(-2, -2) in the x - axis. what are the coordinates of b?

Explanation:

Step1: Recall reflection rule

When reflecting a point $(x,y)$ over the x - axis, the rule is $(x,y)\to(x, - y)$.

Step2: Apply rule to point B

The coordinates of point B are $(1,-5)$. Using the reflection rule, for $x = 1$ and $y=-5$, we get $(1,-(-5))=(1,5)$.

Answer:

$(1,5)$
