Answer 1

The equation would be 32,000 + 700x

Answer 2

Karla's starting salary was $32,200. She gets a $700 raise every year.

Constant increase in salary is $700. so 700 is the rate of increase or slope.

Let x be the number of years and y be the salary .

There is a constant increase in salary every year so we use equation

y= mx + b

Where m is the slope and b is the y intercept

y intercept is the initial salary that is 32,000

m is the rate of increase that is 700

Replace the values of m and b

y = 700x + 32000

The required equation is y= 700x + 32000.
