Set up the problem like this:
y1/x1 = y2/x2
-7/-1 = -84/x2
then use cross multiplication to solve the problem

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
Vera_Pavlovna [14]

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

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

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

The point (18, 18.25) satisfies the equation.

The two points are also plotted on the graph.

If I were solving this equation, I would put x^2-20x+(100)=(10). Since this is in standard form, you could change this into vertex form by making the equation      y=(x-10)^2 -10.
