Answer:
1. m=-4.5
2. See steps below
3. See steps below
4.

Explanation:
1. To simplify equations, distribute terms into the parenthesis by multiplying each term. Then combine like terms and solve using inverse operations.
0.2(m-8) = 0.3m+5-3+0.3m
0.2m - 1.6 = 0.3m + 5 -3 + 0.3m
0.2m - 1.6 = 0.6m + 2
0.2m = 0.6m + 1.8
-0,4m = 1.8
m= -4.5
Apply these same steps to questions 2 and 3.
4. To write the equation of a line, find the slope using the slope formula. Then substitute the slope and a point into the point slope form.
