Renee just began her job as an elementary school teacher. she is told that her starting salary will be $35000 per year. she is also told that her salary will increase to $36960 in 7 years. assume that x = the years worked and y = salary in dollars. what is the rate of change of renee's salary?

Renee's salary begins at $35000 and ends 7 years later as $36960. The salary increase is $1960.

Over 7 years, then, the rate of change of Renee's salary is

$1960

= $280/year.

7 yrs

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
