You can figure out how many boxes Carl will need by dividing the total number of DVDs by the amount of DVDs each box can hold.

Your equation should be: 512 ÷ 20 = x (amount of boxes needed)

512/20 = 25.6

We will round 25.6 up because you cannot have a fraction of a box, so 25.6 becomes 26.

Carl will need 26 boxes.

Passes through the points (−4, 2) and (12, 6)?

<u>I'll assume you need to find the equation of the line that passes through those points.</u>

Answer:

$\displaystyle y-2=\frac{1}{4}(x+4)$

Step-by-step explanation:

<u>Equation of a Line:</u>

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

The given points are (-4,2) and (12,6), thus:

$\displaystyle y-2=\frac{6-2}{12+4}(x+4)$

Operating:

$\displaystyle y-2=\frac{4}{16}(x+4)$

Simplifying, the equation in point-slope form is:

$\mathbf{\displaystyle y-2=\frac{1}{4}(x+4)}$
