Question

Fill in the missing number.2Pieces of Chicken (x) 7 8 6 10Price in dollars (y) 14 16 12 20For each piece of chicken it costs dollars.4

Answer 1

To find the unit rate, we have to use the slope formula.

`m=(y_2-y_1)/(x_2-x_1)`

Let's replace the points (7, 14) and (8,16).

`m=(16-14)/(8-7)=(2)/(1)`

Hence, for each piece of chicken, it costs $2 dollars.
