Answer:
m (slope) = 37
Step-by-step explanation:
use the slope-line formula, y2 - y1/x2 - x1
put in coordinates (5, 20) for x1 and y1
put in coordinates (4, -17) for x2 and y2
simplify
Answer:
First choice: m = -4
Step-by-step explanation:
The second equation is already solved for n, so lets's use the substitution method and substitute m - 2 for n in the first equation.
m - 2n = 8
m - 2(m - 2) = 8
m - 2m + 4 = 8
-m + 4 = 8
-m = 4
m = -4
