You spin the spinner once.
What is P(2 or greater than 1)?
Write your answer as a fraction or whole number.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
