Answers

1) proportional to Mike's tip

2) Not proportional to Mike's tip

3) proportional to Mike's tip

Step-by-step explanation:

when two things have the same relative sides, they are said to be proportional.

To determine if the other tips are proportional to Mikel's tip, we will, first of all, determine the size of Mikel's tip, then compare the other tips with it.

Mikel's tip:

$1.32 for $8.80

=

Now, let us compare this with the other tips

1.) $2.22 for 14.80

=

proportional to Mike's tip

2.) $1.86 for $10.50

Not proportional to Mike's tip

3.) $0.78 for $5.20

=

proportional to Mike's tip

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
