Answer:
read my explanation because this will take a while to put in an answer and explain.
Explanation:
slope: 3x
y-intercept: 48.
equation: y=48-3x
we get this from reading the question.
y=48-3x is your equation! it initially starts at 48, and everytime the hour changes it decreases by 3.
for the table:
0 - 48 5 - 33
1 - 45 6 - 30
2 - 42 7 - 27
3 - 39 8 - 24
4 - 36
the graph you could have filled by yourself, but here:
and when you are done, don't forget to connect the points! i didn't do it because i had to plot them and the line would override it.
