Answer:
The third graph
Step-by-step explanation:
We can immediately eliminate the 1st and last graphs because they are decreasing, not increasing. It wouldn't make sense that the more classrooms there are, the fewer students. Y = 22x would be increasing in the graph.
Let's plug some x values into the equation first, to see where our points are at.
Plug 1 into x
Y = 22(1)
Y= 22
(1,22)
Plug 2 into x
Y = 22(2)
Y = 44
(2,44)
Plug 3 into x
Y = 22(3)
Y = 66
(3,66)
Plug 4 into x
Y = 22(4)
Y = 88
(4,88)
The second graph matches the coordinates, so it works, but it isn't a complete function graph. A function graph needs a line drawn through the points. The second graph isn't your answer.
Let's look at the third graph. The coordinates also match up with the graph and it has a line drawn through the points. It's an accurate function graph representing this scenario. Therefore, the third graph is your answer.
Have a lovely day! :)
