Question

The coordinates of point A on a grid are (−3, −2). Point A is reflected across the y-axis to obtain point B. The coordinates of point B are (___, −2). I need help plzz asp thx

Answer 1

The coordinates of point B are (3,-2)

Explanation:

we know that

The rule of the reflection of a point across the y-axis is given by

(x,y) -----> (-x,y)

so

Applying this rule to the point A(-3,-2)

A(-3,-2) --------> B(3,-2)

therefore

The coordinates of point B are (3,-2)
