A corporate team-building event costs $3, plus an additional $1 per attendee. Write an equation that shows the relationship between the attendees x and the cost y. Write your answer as an equation with y first, followed by an equals sign.

y = $3 + $1x

or

y= 3 + 1x

Step-by-step explanation:

the event cost will be $3 no matter what. For each attendee it cost s $1 more. So you need 1x or $1 for every person.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
