The equation in slope intercept form for the line with slope 3 and Y intercept -1 is y = 3x -1 .
Answer: The copy machine makes 171 copies in 4 minutes and 45 seconds.
Step-by-step explanation:
Let's dissect the question. The copy machine makes 36 copies per minute.
36 per min.
To see how many copies it makes in 4 minutes and 45 seconds, we multiply 36 * 4.75. 45 seconds is 3/4ths of a minute, or 0.75 of a minute.

It makes 171 copies in 4 minutes and 45 seconds.
33/84
if you divide both top and bottom by 3 you will get your simplified answer:
11/28
|-1/5| < |-1/3| < |-7|
Your answer:
B. y = -1/5 x^2; y = -1/3 x^2; y = -7x^2
