5x+y = -23
by substitution
A)
5(-3) + (-4) = -23
-15 - 4 = -23
-19 = -23
Wrong
----------------
B)

Answer:
- The slope of this line is 4
Step-by-step explanation:
The slope is determined with two points.
Take the pairs (0, - 9) and (1, - 5).
The slope is:
- m = (y₂ - y₁) / (x₂ - x₁) = (- 5 - (-9)) / ( 1 - 0) = 4/1 = 4
