The_____of a graph is the difference between any 2 numbers on the scale?

Answer 1

Scale

The scale of a graph is the difference between any two adjacent numbers on the scale. If you select non adjacent numbers then the value is a multiple of the graph's scale, you need to correct your teacher.

Your standard graph has the Real Number line running on the X and Y axis so every Real Number is represented on it.

If you graph the population of the US over time then the typical way to do it is to construct a graph using only the first quadrant, you don't have negative time or negative people (negative population growth still results in a positive number of people living in the US).

The scale of your graph determines the size of it. You can create a 1 to 1 graph that would extend for miles in both directions or you can change the scale. A more handy scale would use a scale of one-hundred-thousands, as the y-axis and a scale of years or decades on the x-axis. The difference between each point on the y-axis would be 100,000 people, and the difference between each point on the x-axis would be either 1 year or 1 decade, depending on which scale you pick.

You can pick any scale to measure any information and the scale that you pick for each axis determines the value between two numbers on the graph line.

The gradient of a graph is the difference between any 2 numbers on the scale?
1)gradient
y2-y1 divide by x2-x1=m/gradient
coordinatesA(4,3)andB(2,-1)
m=4/2=2

Answer 3

Is it possible you mean the 'domain' (which is the difference between the lowest and highest values of 'x') or the 'range' (which is the difference between the lowest and highest values of 'y' ?

Answer 4

error, maybe, i did a physics lab today, you'd think I'd know this.....
