The table shows the cost of a pizza based on the number of toppings. write a function rule to find the cost for a pizza with x toppings

Let y represents the cost of a pizza.

here, x represents the number of topping.

Using slope-intercept form:

The equation of line is given by:

         .....[1]

where, m is the slope of the line and b is the y-intercept.

From the given table:

Consider coordinates in the form of (x, y)

i,e (1, 12) and (2, 14)

Calculate slope:

Substitute the given points we have;

Substitute this in [1] we have;

Substitute any point from the given table to find b:

Substitute (4, 18) we get;

18 = 8+b

Subtract 8 from both sides we have;

10 = b

or

b = 10

⇒

therefore,  function rule represents the  given data table is,

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
