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 rcosθ + rsinθ = 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 (cosθ + sinθ).
In problem 11-23 you determined that x = ? and y = ?
