The formula c = 20x + 5 models the cost of new york yankees t-shirts, where c is the cost and x is the number of shirts sold. choose all true statements in the context of this situation.
the total cost of t-shirts sold represents the domain
this model is a relation but not a function
the total cost of t-shirts sold represents the range
the cost of 20 t-shirts is $405.00 this model is a function

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. : )
