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? $0.57
$1.75
$5.50
$6.50

$1.75

Step-by-step explanation:

(2,3.5) (4,7) pick two points

y=kx+m or y=mx+b

k=y2-y1/x2-x1

7-3.5=3.5

4-2=2

3,5/2=1.75

y=1.75x+m

7=1.75×4+m

m=0

The equation will be y=1.75x+0

we want to know what 1 pen cost

y=cost

x=number of pens

y=1.75×1+0

y=1.75

step-by-step explanation:

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
