A computer disk has a mass of 20 g. How many of these disks would you need to equal a total mass of 1
kg?

60 for the first and 130 for the second

step-by-step explanation:

the absolute value function

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.
