Question

1. if triangle abc was reflected over the y - axis, what would be the coordinates of b?

Explanation:

Step1: Determine original coordinates of B

The coordinates of point B are $(- 3,4)$.

Step2: Apply reflection rule over y - axis

The rule for reflecting a point $(x,y)$ over the y - axis is $(-x,y)$. For point B with $x=-3$ and $y = 4$, when we apply the rule, $-x=-(-3)=3$ and $y$ remains 4. So the coordinates of B' are $(3,4)$.

Answer:

$(3,4)$
