Frieda orders pizzas for a meet at work. Last week she ordered 6
pizzas for $58. This week she ordered 9 pizzas for $82.
Write a point-
slope equation for this scenario. Do not use spaces between any of
your variables or numbers.

Respuesta :

Answer:

[tex]y = 8x + 10[/tex]

Step-by-step explanation:

Given

Represent pizzas with x and amount with y

So:

[tex](x_1,y_1) = (6,58)[/tex]

[tex](x_2,y_2) = (9,82)[/tex]

Required

Determine the point slope equation

First, we need to determine the slope, m

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{82 - 58}{9 - 6}[/tex]

[tex]m = \frac{24}{3}[/tex]

[tex]m = 8[/tex]

Next, we determine the equation using:

[tex]y - y_1 = m(x - x_1)[/tex]

[tex]y - 58 = 8(x - 6)[/tex]

[tex]y - 58 = 8x - 48[/tex]

[tex]y = 8x - 48 + 58[/tex]

[tex]y = 8x + 10[/tex]
