Part A Which graph has the following solution set (-9,10) (-6,5) (0,-5) (3,-10)Part B Write the equation of the graph from part

marysya [2.9K]

$\begin{gathered} \text{Let:} \\ (x1,y1)=(-9,10) \\ (x2,y2)=(-6,5) \\ m=\frac{y2-y1}{x2-x1}=\frac{5-10}{-6-(-9)}=\frac{-5}{3}=-\frac{5}{3} \\ \end{gathered}$

Using the point-slope equation:

$\begin{gathered} y-y1=m(x-x1) \\ y-10=-\frac{5}{3}(x+9) \\ y-10=-\frac{5}{3}x-15 \\ y=-\frac{5}{3}x-5 \end{gathered}$

A baker, in 70 minutes, iced 40 cupcakes and, in 49 minutes, iced 28 cupcakes. What is the constant of proportionality?

Zinaida [17]

Answer:

$\frac{4}{7}$

Step-by-step explanation:

The constant of proportionality is the slope of the line joining the two points

(70,40) and (49,28).

Recall the slope formula:

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

We substitute the point to get:

$m = \frac{28 - 40}{49 - 70} = \frac{ - 12}{ - 21} = \frac{4}{7}$

<u>Alternatively</u>:

A proportional relation is given by

$y = kx$

where k is the constant of proportionality.

Using any point, we substitute and solve for k.

$40 = 70k$

$k = \frac{40}{70} = \frac{4}{7}$
