Question

1.

Choose the linear inequality that describes the graph. The gray area represents the shaded region.


A. y > –3x + 5

B. y > –5x – 3

C. y > –5x + 3

D. y < –5x + 3

Answer 1

D. y < –5x + 3

Explanation:

A. 1st picture

Graph the inequality by finding the boundary line, then shading the appropriate area.

y > − 3 x + 5

B. 2nd picture

Graph the inequality by finding the boundary line, then shading the appropriate area.

y > − 5 x − 3

C. 3rd picture

Graph the inequality by finding the boundary line, then shading the appropriate area.

y > − 5 x + 3

D. 4th picture

Graph the inequality by finding the boundary line, then shading the appropriate area.

y < − 5 x + 3
