Question

Plot the relationship between P and Q on the following graph. P=35-1/4Q

Note: Price (P ) is on the vertical axis and quantity ( Q ) is on the horizontal axis.

Answer 1

The given expression is

`P=35-(1)/(4)Q`

Where
`P` is the price and
`Q` is the quantity. Also,
`P` is the dependent variable and
`Q` is the independent variable.

This expression is modelling a linear relationship between the price and the quantity, if we graph the line that belongs to this equation would be as the image attached.

As you can observe, the relation between these variables is negative, which means that the more quantity, the lower is the price.
