Question

triangle pqr has vertices P(4,-1), Q(-2,7), and R(9,9) find an equation of the median from r find an equation of the altitude r and are ur answers to a and b the same is pqr isosceles

Answer 1

Both equation of the median from R and altitude from R is the same answer: y= (3/4)x + 9/4 so the triangle PQR is an isosceles because because it has two sides of equal length.
