Question

Gina has borrowed 100 songs from her friend. She plans to download an equal number of songs on her music player each week for 5 weeks. The graph shows the number of songs left to download, y, for a certain number of weeks, x:

A graph titled Song Downloading shows Number of Weeks on x-axis and Number of Songs Left to Download on y-axis. The x-axis scale is shown from 0 to 5 at increments of 1, and the y-axis scale is shown from 0 to 140 at increments of 20. A straight line joins the ordered pairs 0, 100 and 1, 80 and 2, 60 and 3, 40 and 4, 20 and 5, 0.

Answer 2

whats part b ?

Answer 3

Part B: Write an equation in slope-intercept form to model the relationship between x and y. (4 points) sorry lol I didn't copy it on

slope intercept form is y=mx+b

m being the slope and b being the y intercept

Answer 5

so the slope was -20

Answer 6
