First, write the equation of the line.

Let's find the y-intercept.

  • => y = mx + b
  • => y = mx + 5

Now, let's find the slope.

  • My chosen points: (1,2) and (-1,2)

Finding the slope:

  • Rise/Run = -3/1 = -3

Our equation: y = -3x + 5

Now, let's change the sign to "≤" because that will tell us the area of the gray region. If we were using the sign "≥", that would find the area of the blue region.

Linear inequality = y ≤ -3x + 5

Option B is correct.
