The straight line through two points will have an equation in the form \(y = mx + c\). Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into ...

Sketch the curve whose polar equation is \(r=-1+\cos \theta\text{,}\) indicating any symmetries. Mark on your sketch the polar coordinates of all points where the curve intersects the polar axis.

Then, we can find the value of \(c\), the \(y\)-intercept, by substituting the coordinates of one point into the equation. The final answer can be checked by substituting the coordinates of the ...
