Answer:
y ≥ 3x - 1
y <
Step-by-step explanation:
Let the equation of the solid line passing through (x', y') given in graph is,
y = mx + b
Here m = slope of the line
b = y-intercept
Slope of the solid line =
m =
m = 3
y - intercept 'b' = -1
Therefore, equation of the line will be,
y = 3x - 1
Since, shaded (blue) area is above the line, inequality that will represent the solution area will be,
y ≥ 3x - 1
For the dotted line,
Slope of the line (m) =
=
=
y-intercept (b) = 2
Equation of the dotted line → y =
Since, shaded (grey color) area is below the dotted line,
Inequality representing the solution area will be,
y <
