Answer:
a = c + 16
Step-by-step explanation:
a = b + 12
b = c + 4
Solve for b in the first equation.
a = b + 12
a - 12 = b
Put b as a - 12 in the second equation and solve for a.
a - 12 = c + 4
a = c + 4 + 12
a = c + 16
Answer:
-2/5
2
Step-by-step explanation:
Slope is rise over run according to my former algebra teacher, but I learned it differently (still correct tho).

The second one moves 2 x-units for every 1 y-unit, so the slope is 2,
