7-22.

On graph paper, graph Δ

*ABC*if its vertices are*A*(–2, 7),*B*(–5, 8), and*C*(–3, 1).*7-22 HW eTool*(Desmos). Homework Help ✎Reflect Δ

*ABC*across the*x*-axis to form Δ*A*′*B*′*C*′. Name the coordinates of each new vertex.Now rotate Δ

*A*′*B*′*C*′ 180° about the origin (0, 0) to form Δ*A*″*B*″*C*″. Name the coordinates of each new vertex.Describe a single transformation that would map Δ

*ABC*to Δ*A*″*B*″*C*″.
