A gift card stores data using a black, magnetic stripe on the back of the card. Find the width w of the stripe.

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.

43

step-by-step explanation:

not sure if this is supposed to be a trick question. 43 is the only one that makes any sense.
