Janine tells her friend that ordered pairs that have an x-coordinate of 0 lie on the x-axis. she uses the origin as an example. discribe jaine's error. use a counter example to explain why she is wrong

The correct answer is:

The x-coordinate of an ordered pair tells us how many units to go left or right from the origin. If the x-coordinate is positive, we go right; if it is negative, we go left.

The y-coordinate of an ordered pair tells us how many units to go up or down from the origin. If the y-coordinate is positive, we go up; if it is negative, we go down.

If we are on the x-axis, this means we have not gone up or down any from the origin. This means the y-value did not change, and the y-coordinate is 0.

Take the point (0, 3). To plot this point, we do not go over from the origin, but we go up 3. This point is not on the x-axis.

However, consider the point (3, 0). To plot this point, we go over 3 from the origin, but do not go up or down any. This point is on the x-axis.

Any point on the x-axis has a y-coordinate of 0.

why do wages differ across industries

step-by-step explanation :

micro economists are concerned with economics on an industry or individual firm basis.

macro economists are concerned with national and international level
