Not sure what to do help ??

N = 4M

-> See attached

Step-by-step explanation:

[] He needs to read 4 each month and N is the number of novels needed to read in M months

  -> If M = 1, then N = 4

  -> Using this logic we can see that if M = 2, N = 8

  -> Using these two points, we can graph a line and get an equation

[] N = 4M

  -> The slope is 4, after every month (our x value) a value of 4 will be added as four more books were read

  -> This equation is in y = mx + b form, but there is no y-intercept (b) and the y and x values have been changed to N and M for this problem

[] Still confused about how I got there?

  -> For every month, 4 books must be read. So, after M months, the books needed to be read will be 4 books times the number of months. In other words, 4M. Books needing to be read is equal to N, hence completing the equation.

Have a nice day!
