13. model the function rule y = -2x - 3 with a table of values. show your work.

y = -2x - 3

To make a table, we assume any number for x  and find out y

Lets assume x= -1

y = -2x - 3 = -2(-1) -3 = 2-3 = -1

Lets assume x= 0

y = -2x - 3 = -2(0) -3 = 0-3 = -3

Lets assume x= 1

y = -2x - 3 = -2(1) -3 = -2-3 = -5

Lets assume x= 2

y = -2x - 3 = -2(2) -3 = -4-3 = -7

Table is

x      y = -2x-3

-1       -1

0        -3

1        -5

2       -7

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
