A system of linear equations includes the line that is created by the equation y = 0.5x-1 and the line through the points (3, 1) and (-5, 7) What is the solution to the system of equations?
(-6,-4)
(0,-1)
(0, -2)
(2.0)

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

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 this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

22
