Use the graph to write a linear function that relates y to x.

y = − 2 x + 1 y=-2x+1 y = − 2 x + 1

y = − 1 2 x + 1 y=-\frac{1}{2}x+1 y = − 2 1 x + 1

y = 1 2 x + 1 y=\frac{1}{2}x+1 y = 2 1 x + 1

Use the table to write a linear function that relates y to x.

y = − 1 3 x y=-\frac{1}{3}x y = − 3 1 x

y = 1 3 x y=\frac{1}{3}x y = 3 1 x

Write a linear function that relates y to x . How long does it take to make 7 burritos?

y = 0.75 x y=0.75x y = 0 . 7 5 x ; 5.25 minutes

y = 0.75 x y=0.75x\ y = 0 . 7 5 x ; 7.5 minutes

y = 4 3 x y=\frac{4}{3}x y = 3 4 x ; 9.3 minutes

y = 1.3 x y=1.3x y = 1 . 3 x ; 13 minutes

The number of minutes it takes to make one burrito.

The number of burritos you can make per minute.

The cost (in dollars) for every one burrito.

You can make 4 burritos in 3 minutes.
