On a math test a student, Sarah, has to identify all the coefficients and constants of the expression 9n+b+2. Sarah says that 9 is a coefficient and 2 is a constant. Identify all the coefficients and constants of the expression. What error might Sarah have made? The coefficient(s) of the expression is/are
(Use a comma to separate answers as needed.)

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.

it would be 3 ÷by 6 because the number on each side
