Amber received an end of year bonus of $2500 at work, and went on a shopping spree. She spent $125 at the department store, $345 at the home furnishing store, and $21 at the card shop. How much of her bonus does Amber have left?

$2009

Step-by-step explanation:

125+345+21=491

2500-491=2009

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
