Question

Which point on the graph shows the price of 6 ounces of cheese? Use the formula y=x÷2 to find y when x is 6.

Answer 1

The value of y is 3 when x is 6.

Solution:

The given table is the amount of cheese in ounces and the cost price.

Let x represents the amount of cheese and y represents the cost price.

The formula which derived from the table is y = x ÷ 2.

That is $y=\frac{x}{2}$.

To find the value of y when x is 6:

$y=\frac{x}{2}$

Substitute x = 6 in the formula, we get

$y=\frac{6}{2}$

y = 3

Hence the value of y is 3 when x is 6.
