Part A: I feel like the answer is a box plot, but I can't remember how to do that. But I would kinda say a histogram( basically a bar graph) because you would be able to see how many students had each score. Part B: One the bottom it would be , Students' scores: 4,3,2... On the side it would be, The number of How MANY students got each score.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
