i think the answer is 4 but im not sure
Answer:
The answer to your question is y < -2x + 3
Step-by-step explanation:
See the graph below
Process
1.- Find the slope

Substitution



2.- Find the equation of the line
y - y1 = m(x - x1)
Substitution
y - 3 = -2(x - 0)
Simplify and solve for y
y - 3 = -2x
y = -2x + 3
3.- Write the inequality
As the left area of the plane is shaded the inequality must be
y < -2x + 3
