Since the triangle is isosceles, the two legs have equal length. The coordinates of two vertices are given P(3,3) Q(3,1) Assuming that PQ and QR are the legs of equal length, the distance between Q and R must be the same as the distance between P and Q d = √[(3-3)² + (3-1)² d = 2 Therefore, the coordinates of P is (5,1)
The graph of a linear equation can either run uphill or downhill. The slope is positive when the line is uphill, while the downhill line represents a negative slope. To find the slope, find two coordinates along the line.
