Answer:

  ratio: $140/(7 calculators)

  unit rate: $20/calculator

Step-by-step explanation:

For rates involving prices, we're usually interested in the price per item, so we divide the cost by the number of items to form the appropriate rate. Simplified, it is the unit rate.

  ratio = $140/(7 calculators) = $20/calculator = unit rate

___

A "unit rate" is a rate with 1 (unit) in the denominator.

"per" can usually be considered to mean "divided by" in this context. As in "price per item" means "price divided by items".

Identify the slope and y-intercept of the line x+2y=−2.
Reil [10]

Answer:

slope: -1/2

Y-intercept: -1

Step-by-step explanation:

Get Y by itself by subtracting x on both sides

2y= -x -2

Now divide both sides by 2 to cancel the two connected to the y:

Y = -1/2x -2/2

So y= -1/2x -1

Y=mx+b so m is the slope and b represents the y-intercept
