Answer:
Graph the equation is shown below.
Step-by-step 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](https://tex.z-dn.net/?f=y%3D0.50x%2B9.25)
Here,
<em>y </em>= cost of the pizza
<em>x</em> = number of toppings
The graph of the linear equation is shown below.
Consider the point (2, 10.25).
When <em>x</em> = 2 compute the value of <em>y</em> as follows:
![y=0.50x+9.25\\=(0.50\times 2)+9.25\\=10.25](https://tex.z-dn.net/?f=y%3D0.50x%2B9.25%5C%5C%3D%280.50%5Ctimes%202%29%2B9.25%5C%5C%3D10.25)
The point (2, 10.25) satisfies the equation.
Again consider a point (18, 18.25).
When <em>x</em> = 18 compute the value of <em>y</em> as follows:
![y=0.50x+9.25\\=(0.50\times 18)+9.25\\=18.25](https://tex.z-dn.net/?f=y%3D0.50x%2B9.25%5C%5C%3D%280.50%5Ctimes%2018%29%2B9.25%5C%5C%3D18.25)
The point (18, 18.25) satisfies the equation.
The two points are also plotted on the graph.
