Select all equations whose graphs are lines perpendicular to the graph of \(3x+2y=6\).

Match each line with a perpendicular line. 

Select all points on the line with a slope of \(\text-\frac{1}2\) that go through the point \((4,\text-1)\).

One way to define a circle is that it is the set of all points that are the same distance from a given center. How does the equation \((x-h)^2+(y-k)^2=r^2\) relate to this definition? Draw a diagram if it helps you explain.
