For lunch, Ruby orders the items shown below Ham and cheese sandwich $4.95 Apple $1.00
Iced Tea $2.50
If the sales tax on all food and drinks is 11.0%, to the nearest cent, what is the total cost of Ruby's lunch?

9.38

Step-by-step explanation:

I added them all up and then found what 11 percent of all of that was. Rounded it up and added it to the total.

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

remember about y=mx+b so she’s forgot to put the 3x to a fraction
