Estimate the area of the irregular shape.

Explain your process for calculating the area of the above irregular image.

What is the slope of line segment PQ with coordinates P(-2,5) and Q(-1, 1)?

What is the slope of line segment QR with coordinates Q(-1, 1) and R(7,3)?

What is the slope of line segment PR with coordinates P(-2, 5) and and R(7,3)?

The coordinates of the vertices of triangle PQR are P(-2, 5), Q(-1, 1) and R(7,3). Determine whether triangle PQR is a right triangle. Use the work from questions 3, 4 and 5 to help you with this question.
