Answer:

(-5,1)

Step-by-step explanation:

To eliminate x, multiply the first equation by 3 and add 2 times the second equation.

3(-2x +7y) +2(3x -4y) = 3(17) +2(-19)

-6x +21y +6x -8y = 51 -38

13y = 13

y = 1 . . . . . matches the third answer choice

(x, y) = (-5, 1)

zhannawk [14.2K]

Answer:

Any points on the line y=2/5 x - 6/5. See picture below.

Step-by-step explanation:

Convert the equation to slope intercept form and graph it.

2x - 5y = 6

-5y = 6 - 2x

y = -2/-5 x + 6/-5

y=2/5 x - 6/5.

Locate each of the points listed on the graph. If they are a part of the line, then they are solutions.
