Show that the line of slope t through (1, 0) intersects the unit circle in the point

Question:

Show that the line of slope t through (−1, 0) intersects the unit circle in the point with coordinates

x = 1 - 1 1 + 1' y = 2t 1 + 1

Conclude that these equations parametrize the unit circle with the point (−1, 0) excluded (Figure 24). Show further that t = y/(x + 1).

(-1,0) (x, y) Slope t -X
