The slope can sometimes be called the gradient, and the equation for the gradient is (y2 - y1)/(x2 - x1). So therefore, you'd do: (-8 - 7)/(4 - -5) which is (-15)/9) which is -1 2/3 or -1.6 (recurring), which is your answer. I hope this helps! Let me know if I've confused you :)
13 songs per cd 4/4 and 52/4= 1/13
so I think 37\12 is the answer to this question
The initial membership fee before any months are considered is 35.
Substitute 0 with x because no months have been considered. Like what was previously said, y is the total cost, so:
Y=12(0)+35
12 x 0 = 0
Y=0+35
Y=35
If you search the internet you can find the answer I hope you can find the answer
