Question

Frieda orders pizzas for a meet at work. Last week she ordered 6

Answer 1

Answer:

$y = 8x + 10$

Step-by-step explanation:

Given

Represent pizzas with x and amount with y

So:

$(x_1,y_1) = (6,58)$

$(x_2,y_2) = (9,82)$

Required

Determine the point slope equation

First, we need to determine the slope, m

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{82 - 58}{9 - 6}$

$m = \frac{24}{3}$

$m = 8$

Next, we determine the equation using:

$y - y_1 = m(x - x_1)$

$y - 58 = 8(x - 6)$

$y - 58 = 8x - 48$

$y = 8x - 48 + 58$

$y = 8x + 10$
