Who has a greater responsibility in a democracy- the government or the people?

I feel this question is based on opinion, but it matters in context. In european countries its the people. In America its the government.

It must have the same slope as the given line, so

m = -A/B = -1/-2 = 1/2

So far, we have

y = mx + b = x/2 + b

Use the given point to find b.

4 = -2/2 + b = -1 + b

b = 5

y = x/2 + 5

Multiply through by 2.

2y = x + 10

Standard form:

x - 2y = -10
