The graph is a straight line with slope = 12.5 and y-intercept = 100. 'm' is the number of months after you start this savings plan.
b). The part of the Real Estate ad that tells us the cost of land on Mars is cut off. However much 10 acres will cost, put that number into the equation where it says "Balance in my account", and solve the equation for 'm'.

b). No. The value n = 3.5 does not make sense in the context of the problem. We're talking about polygons with 'n' sides, and it's very hard to draw or imagine a polygon with 3.5 sides.
