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 < 
Answer: omg this is hard
Step-by-step explanation:
M(x, y) = ((x1 + x2)/2, (y1 + y2)/2) = ((-2 + 4)/2, (5 - 9)/2) = (2/2, -4/2) = (1, -2)
