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.
