Answer:

(1, - 5)

Step-by-step explanation:

To determine which ordered pair is a solution

Substitute the x value into the right side of the equation and if the value is equal to the y- coordinate of the point then it is a solution.

(1, - 5)

y = - 4(1) - 1 = - 4 - 1 = - 5 ← True

(4, 15)

y = - 4(4) - 1 = - 16 - 1 = - 17 ≠ 15

(2, - 7)

y = - 4(2) - 1 = - 8 - 1 = - 9 ≠ - 7

(- 5, 1)

y = - 4(- 5) - 1 = 20 - 1 = 19 ≠ 1

(1, - 5) is a solution to the equation y = - 4x - 1

#2
2x - 4y = -2
2x + 3y = -16
------------------subtract
-7y = 14
y = 14/-7
y = -2

2x - 4y = -2
2x - 4(-2) = -2
2x + 8 = -2
2x = -2 -8
2x = -10
x = -10/2
x = -5
answer x = -2 and y = -5

check:

2(-5)- 4(-2) = -2
-10 +8 = -2
-2 = -2.....true

2x + 3y = -16
2(-5)+3(-2) = -16
-10 + (-6) = -16
-16 = -16...true
