Your answer should be C sorry if i'm wrong, hope it helps tho
<h3><u>
Answer:</u></h3>
Option: C is the correct answer.
c) the coefficient of x is positive
<h3><u>
Step-by-step explanation:</u></h3>
We know that graph of a line goes up and to the right when the coefficient of x is positive.
Since we know that when a line goes up and to the right this means that the line is increasing and hence we will get a positive slope of the line and we know that the slope intercept of a line is given as:

as m is positive this means that:
the coefficient of x is positive.
Hence, the correct answer is:
c) the coefficient of x is positive
I believe that the smallest number of students Jimmy can measure is 223, and I know this is right because one of my teachers had us do this probem and she said this was it.
You would need the table to figure this problem out, but here we go!
15000×.018= 270
15000×.020= 300
15000×.023= 345
270+300+345= $915
