Mia had $22. then she started to receive $4 a week as an allowance. she plans to save all of her money for a bicycle and draws a graph of her planned savings. mia lets x represent the number of weeks she has received her allowance, and y represent her total amount of money. which of the following ordered pairs is on mia's graph?

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

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
