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

astra-53 [7]
Charmaine= x
William=x+3
3 times Charmaine = 3x
2times William = 2x+6
5x+6=76
5x=76-6
5x=70
X=14
Charmaine is 14
William is 3 years older so is 17

Check:
17x2= 34
14x3=42
34+42=76

So Charmaine is 14
William is 17

Basile [38]
Equation - x = -3/10 + (10-1)

The original number is 9.3 because
x = -3/10 + (10-1)
x = -3/10 + 9
x = 9.3
