For question 3, the slope would be -5
Step-by-step explanation:
If you wanted to graph this you would have to plot one of the points that is already given. Then from that point, you would move 5 units down and 1 unit to the right. If you run out of space, you can go to the other direction by going 5 units up and 1 to the left.
Hope this helps :)
The equation will be y=4/x. u can make the table of variables by inserting the values of x in the equation. for suppose here, if x=1 then y=4 , x=2 then y=2 and so on.
ANSWER
30 students
EXPLANATION
The cost per student varies inversely as the number of students.
Inverse proportion is written as:

Let the cost per student be y.
Let the number of students be x.
It will cost each student $250 if 24 students attend. This means that:

If the cost is down to $200, it means that y is now $200.
That is:

Therefore, 30 students could attend.

65 is 52% of 125.
I do the IS over OF operation when finding a percentage, where you multiply the is by 100 then divide by the percentage.
