What is the solution of the system of equations? Explain. y = 1/2x + 4
2y + 4 = x
A. Infinitely many; the lines are the same.
O
B. There is no solution; the lines are parallel.
C. There is no solution; the lines are perpendicular.
D. (0, 4); the lines intersect at this points.

the answer is c. 23/3

the f

last graph i believe

step-by-step explanation:

worked it out i believe

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.
