Question

What is the solution to the following system of linear equations?

A) (2, 1)
B) (1, 2)
C) (-2, -1)
D) (-1, -2)

Answer 1

a2x + b2y = c2
where a1 = 1, by = k+ 1, c = 5
and a2 = k + 1, b2 = 9 and c2 = 8k - 1

Answer 2

C) (-2, -1)

Explanation:

The graphs meet at the point (-2, -1), therefore C is the solution.
