Answer:
243
Step-by-step explanation:
3x3=9
9x3=27
27x3=81
81x3=243
For this case we have the following system of equations:
y = x + 5
y = -2x - 1
Substituting the point (-2, 3) we have:
For Line C:
y = x + 5
3 = -2 + 5
3 = 3
The line goes through this point.
For Line D:
y = -2x - 1
3 = -2 (-2) - 1
3 = 4 - 1
3 = 3
The line goes through this point.
Answer:
(-2, 3), because both lines pass through this point
