Determine whether the given number is an irrational number or a rational number and place it in it’s representing category

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.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
