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)
Point slope formula:
(y₂ -y₁) = m(x₂ - x₁)
(1 - 0) =
(4 - X)
1 =
-1 = X
(y₂ -y₁) = m(x₂ - x₁)
(1 - 0) =
1 =
-1 = X
