The vertices of ∆PQR are P(–3, 8), Q(–6, –4), and R(1, 1). If you reflect ∆PQR across the x-axis, what will be the coordinates o
f the vertices of the image ∆P′Q′R′?
1 answer:
Answer:
P'(–3, -8), Q'(–6, 4), R'(1, -1).
Step-by-step explanation:
When you reflect a point (x, y) across the x-axis, the x-coordinate remains the same, but the y-coordinate gets the opposite sign.
The rule is
(x,y) ⟶ (x,-y)
Thus,
P(-3,8) ⟶ P'(-3, -8)
Q(-6,-4) ⟶ Q'(-6, 4)
R(1,1) ⟶ R'(1, -1)
The coordinates of the image triangle are:
P'(–3, -8), Q'(–6, 4), R'(1, -1)
The diagram below shows your source and image triangles. The red and blue arrows show how the points moved during the reflection.
