y ≤ 3x - 1y ≥ - x + 4
Step-by-step explanation:
On the graph we have:
Line f(x)f(x) is rising function, y-intercept is -1, slope is 3 which is determined by the points - (0, -1) and (1, 2)Zone B is to the right of the line and the line is solid
As per description above we get inequality:
y ≤ 3x - 1Line g(x)g(x) is decreasing function, y-intercept is 4, slope is -1 which is determined by same x-intercept and y-interceptZone A is to the right of the line and the line is solid
As per description above we get inequality:
y ≥ - x + 4
Zone AB is the intersection of the two zones, so the system is:
y ≤ 3x - 1y ≥ - x + 4
