At the end of a party, there was a 1/2 pizza left over. 7 friends decided to divide the leftover pizza equally. What fraction of the whole pizza did each friend have?​

1) is right

step-by-step explanation:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

what statement? is there an image?

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.
