Question

Which equation does the graph of the systems of equations solve? two linear functions intersecting at 2, negative 3 A. one half x + 4 = 2x − 1 B. −one half x + 4 = −2x − 1 C. −one half x − 4 = 2x − 1 D. one half x − 4 = −2x + 1

Answer 1

The solution to this system is (x,y) = (2,-3)

D. one half x − 4 = −2x + 1

>>>  x/2 - 4 = y...........> (2)/2 -4  = -3
>>> -2x + 1    = y  ......> -2(2) +1 = -3

Result that we can check in the graph below.
