Step 1

Find the equation of the line

The formula to calculate the slope between two points is equal to


m=(y2-y1)/(x2-x1)

we have


A(0,3)\ B(2,-3)

Substitute the values


m=(-3-3)/(2-0)


m=(-6)/(2)


m=-3

The equation of the line in slope-intercept form is equal to


y=mx+b

where

m is the slope

b is the y-intercept

we have


m=-3


b=3 ------> see the graph

substitute


y=-3x+3

Step 2

Find the equation of the inequality

we know that

The solution of the inequality is the shaded area below the solid red line

so

the inequality is


y\leq -3x+3

therefore

the answer is the option C


y\leq -3x+3
