EXAMPLE 5 Calculating Distance (a) The distance between P(-1, 2) and 0(3, 4) is V(3 - (-1))² + (4 – 2) = V(4 + (2)² = V/20 = V4.5 = 2V5. (b) The distance from the origin to P(x, y) is V - 0)² + (y – o) = Vx² + y?. 21 Exercises1.2: Write an equation for each line described. 1. Passes through (-8,0) and (-1,3). 2.
