Which is true given the two equations below?

3(1) - 8(-2) = 19
7(1) - 5(-2) = 17
a.
(19, 17) is the intersection point of the graphs of
3x - 8y = 19 and 7x - 5y = 17.

b.
(19, 17) is the intersection point of the graphs of
x - 2y = 19 and x - 2y = 17.

c.
(1, -2) is the intersection point of the graphs of
3x - 8y = 19 and 7x - 5y = 17.

d.
(1, -2) is the intersection point of the graphs of
x - 2y = 19 and x - 2y = 17.

Written as a simplified polynomial in standard form, what is the result when (2x+8)^2(2x+8) 2 is subtracted from 8x^2-38x 2 −3?
