Answer:

The answer to you question is a) 3. 4x + 3y ≤ 8 b) (-1, 4)

Explanation:

Process

From the graph, get two points

A (-1, 4)

B (2, 0)

1.- Find the equation of the line

m = (4 - 0) / (-1 -2)

m = -4/3

y - 0 = -4/3(x - 2)

3(y - 0) = -4x + 8

3y - 0 = -4x +8

4x + 3y = 8

2.- Convert the line to an inequality

4x + 3y ≤ 8 Because we are interested in the area below the line.

Second part

The only point that satisfies the inequality is (-1, 4)
