Answer:

y < 4x - 2

Step-by-step explanation:

Determine the equation of the line:

  • Choose two points on the line: (1, 2) and (0, -2)
  • Calculate the slope
    Slope  = change in y ÷ change in x = (-2 -2) ÷ (0 - 1) = -4 ÷ -1 = 4
    Therefore, y = 4x + b (where b is the y-intercept)
  • From inspection, y-intercept = -2
  • So equation of the line: y = 4x - 2

A solid line means the signs ≤ or ≥ should be used (inclusive boundary)

A dotted line means the signs < or > should be used (non inclusive boundary).

> is points above the boundary line

< is points below the boundary line

Therefore, the grey shaded area is y < 4x - 2
