Question

Given a triangle with vertices A(4, -1), B(-3,0), and C(7,2), which points represent a

reflection of Triangle ABC in the y-axis?
O A(4,1), B(-3,0) (7,-2)
O None of the other answers are correct
O A(-4,-1), B(3,0), C(-7,2)
O A(-1,4), B(0, -3). C(2,7)
O A(-4,1), B(3,0), C(-7, - 2)

Answer 1

A(-4,1), B(3,0), C(-7, - 2)

Explanation:

When we reflect on the y-axis, we simply negate the value of the x-axis coordinate

Thus;

(x,y) becomes (-x,y)

So the correct answer is the coordinates that negates the x/axis values

(4,-1) becomes. (-4,-1)

(-3,0) becomes (3,0)

(7,-2) becomes (-7,-2)
