12 computers are produced per day and the proportionality can be expressed by y = 12x where x represents no. of days and y represents no. of computers.
In co-ordinate planes we can graph our equations by use of given co-ordinate points and joining them.
According to the given question on a coordinate plane, the x-axis is labelled Number of Days and the y-axis is labelled Number of Computers. A line goes through points (3, 36), (4, 48), (5, 60).
We can observe from the given graph is that in every next day 12 computers are produced. Also if we divide the total no. of computers to the total no. of days the computers produced per day will also be 12.
