The graph below shows the cost of pens based on the number of pens in a pack. what would be the cost of one pen

$6.75
$3.37
$1.25
$0.80

C. $1.25

Step-by-step explanation:

We have been given a graph that shows the cost of pens based on the number of pens in a pack. We are asked to find cost of one pen.

The cost of one pen would be equal to slope of line that connects the given points.

First of all, we will find slope of our given line using points and in slope formula.

, where,

= Difference between two y-coordinates,

= Difference between two x-coordinates of same y-coordinates.

Upon substituting our given values in slope formula, we will get:

Therefore, the cost of one pen is $1.25 and option C is the correct choice.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

hope this !
