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!

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

70.30
