Question

A small pizza at Little Italy pizzeria costs $9.25, and each topping is an additional $0.50. So the cost of ordering a pizza can be determined by the equation y=0.50x+9.25, where y represents the cost of the pizza, and x represents the number of toppings.

Graph the equation by finding two points that satisfy the equation and plotting them on the graph.

Answer 1

Graph the equation is shown below.

Explanation:

The linear equation representing the relation between cost of ordering a pizza and the number of additional toppings is:

`y=0.50x+9.25`

Here,

y = cost of the pizza

x = number of toppings

The graph of the linear equation is shown below.

Consider the point (2, 10.25).

When x = 2 compute the value of y as follows:

`y=0.50x+9.25\\=(0.50* 2)+9.25\\=10.25`

The point (2, 10.25) satisfies the equation.

Again consider a point (18, 18.25).

When x = 18 compute the value of y as follows:

`y=0.50x+9.25\\=(0.50* 18)+9.25\\=18.25`

The point (18, 18.25) satisfies the equation.

The two points are also plotted on the graph.
