Juanita makes leather lanyards to sell. She charges a base fee and a cost per inch of the finished lanyard. The line shows the cost y for x inches of lanyard. Write an equation for the line in slope-intercept form.

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. : )

step-by-step explanation:

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
