Question

Choose scales for the coordinate plane shown so that you can graph points J(2,40), K(3,10), L(3,-40),M(-4,50) and N(-5,-50). explain why you chose the scale for each axis

Answer 1

The scale of y-axis is 10, and the scale of x-axis is 1.

Explanation:

The y-coordinates of points J, K,L,M, and N are divisible by 10, so it would be convenient to scale the y-axis to 10, doing so will result in a graph that does not occupy too much space and is therefore easier to read.

The x-coordinates of points J, K,L,M, and N are integers less than 10. Our graph will be easier to read if we scale the x-axis to 1, because then we get a graph whose x-coordinate is marked such that the x values of the points can be easily related.
