A linear function r models the growth of your right index fingernail. The length of the fingernail increases 0.7 millimeters every week . Graph r when r (0)=12. Identify the slope and interpret the y- intercept.

i'm sure goog can you get that answer

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.
