Answer:
A
Step-by-step explanation:
the equation of the line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 3, 3 ) and (x₂, y₂ ) = (0, 1) ← 2 points on the line
m =
=
= - 
the line crosses the y- axis at (0, 1 ) ⇒ c = 1
y = -
x + 1 ← equation of line
the solutions to the inequality lie above the line, including the line, in the shaded area , then
y ≥ -
x + 1 → A
