18x - 5y = -14
9x - Зу = -12

I need 2 points (x, y)
solve using elimination​

x=2

y=10

Step-by-step explanation:

I use Symbolad it helps a lol

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

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.
