Question

Garrett already has 5 bracelets made to sell at the craft fair. After working for 3 hours, he has a total of 11 bracelets made to sell at the craft fair. Write an equation in slope-intercept form where x represents the amount of time he spent making bracelets and y represents the number of bracelets made. How could you use the equation to predict the number of bracelets he will have made if he works for 5 hours?

A. y = 3x + 11; substitute 5 for x
B. y = 11x + 5; add 5 to the value of y
C. y = 5x + 2; add 5 to the value of y
D. y = 2x + 5; substitute 5 for x

Answer 1

Answer Choice D. He will make 10 bracelets in 5 hours (for the other question).

Explanation:

He makes 2 braclets and hour so the slope is 2. He already has 5 bracelets so the y-intercept is 5.

Answer 2

y = 2x + 5; substitute 5 for x
