Answer:
1. (-4, 1)
2. I substituted (y = x + 5) into (3x + y = -11) first before substituting the value of x into (y = x + 5) to find the value of y.
Step-by-step explanation:
Substitute y = x + 5 into 3x + y = -11:
3x + y = -11
3x + x + 5 = -11
4x + 5 = -11
4x = -11 - 5
= -16
x = -16 ÷ 4
x = -4
Substitute x = 4 into y = x + 5:
y = x + 5
y = -4 + 5
y = 1
A coordinate point is written like this: (x, y)
Thus, the final answer is: (-4, 1)
