Some algebra will show us why. Since the line has slope 2 and y -intercept 5, we can write its equation as y = 2 x + 5. The equation of the circle is x2 + y2 = 25, so to find the points of ...

There is a trick to measure the area of a circle. In fact, this was a trick people used in the past to find the area under a curve on a graph (before technology gave us better methods). Suppose I ...
