Answer:

Explanation:
-40 - 6m + 1 = - 2
- Simplify Both Sides Of The Equation
−40 − 6m + 1 = −2
−40 + −6m + 1 = −2
(−6m) + (−40 + 1) = −2 (Combine Like Terms)
−6m + −39 = −2
= −6m − 39 = −2
−6m − 39 + 39 = −2 + 39
−6m = 37
-6m / -6 = 37 / -6

Answer:
A. 4
Step-by-step explanation:
Constant of proportionality (k) = y/x
We can use the coordinates of any point on the line to find k.
Let's use (2, 8)
Constant of proportionality (k) = 8/2
Constant of proportionality (k) = 4
