On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 3, 1) and (0, 3). Everything to the left of the line is shaded. Which linear inequality is represented by the graph? y < Two-thirdsx + 3 y > Three-halvesx + 3 y > Two-thirdsx + 3 y < Three-halvesx + 3

Answer:


y>(2)/(3)x+3

Explanation:

step 1

Determine the slope of the dashed line

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


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

we have

(-3,1) and (0,3)

substitute


m=(3-1)/(0+3)


m=(2)/(3)

step 2

Find the equation of the dashed line in slope intercept form


y=mx+b

we have


m=(2)/(3)


b=3 ---> given problem

substitute


y=(2)/(3)x+3

step 3

Find the equation of the inequality

we know that

Is a dashed line and everything to the left of the line is shaded

so


y>(2)/(3)x+3

see the attached figure to better understand the problem
