Answer:
x = 1 y = -4
Step-by-step explanation:
- Plug the value of y into the other equation.
x + 3y = -11
x + 3(-4x) = -11
x - 12x = -11
-11x = -11
x = 1
- Now substitute the value of x into any equation.
y = -4x
y = -4(1)
y = -4

Answer:
2/5
Step-by-step explanation:
To find slope:
y2-y1 / x2-x1
2-6 / -12--2
2-6 / -12+2
-4/-10
4/10
2/5
Answer:
