Well we can use $ left as the y axis and the amount songs purchased as the x axis. First we are going to divide 20 by 16 to get 1.25 which means that each song is $1.25. *Which means after 16 songs on the x axis the lone should be at the bottom at point (0, 0).* Your equation is y=20-1.25x If you need more information just let me know :)
Answer:
either b or a
Step-by-step explanation:
Answer:
You have to find the slope first. Which is y1-y1 divided by x1-x2
Then you find the y-intercept which you take the slope for m like for example if you find the slope, 2, then the equation should be y=2x+b. You take the coordinates on the problem and put them on the y or x on the equation. Then when you find the y-intercept you add it to the equation like for the example that I used above, you have to put the y-intercept on b. So if the y-intercept is 5 then the equation would be y=2x+5.
2.85 = 2 17/20 - hope it helps!
Slope = (y2 - y1)/(x2 - x1)
Let's plug in our values: (10 - 9)/(5 - - 6)
This gives us 1/11 as our slope.
