Need help please!
I know the first answer is 19 as it is going up by 3 each time. For the second answer I have tried 3n and n+3 and n= 3 but it isn’t accepting the answer any help appreciated!

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.

for future students the answer is b

hope i
