11-24.

Earlier you graphed

*r*=, which gave a graph that looked like a straight line. Complete the problems below to see why this is true. Homework Help ✎ Explain why the equation can be rewritten as

*r*cos*θ*+*r*sin*θ*= 5.Use the results of the previous problem to show that the equation in part (a) is

*y*= 5 −*x*.

Multiply both sides of the equation by (cos*θ* + sin*θ*).

In problem 11-23 you determined that *x* = ? and *y* = ?
