What does the slope of the line represent within the context of your graph?
What labels are assigned to the x- and y-axes of the graph?
Point A and Point G
is that what you are looking for? I am not really good at this
What kind of data is this? The point (9,65) is graphed. Could that be 9 is the number of hours worked and 65 is the pay for those hours? That is what I mean by labels.
The attached sample graph has a title. The x-axis is labeled and so is the y. That gives the graph context.
oh I had to graph measurements how tall people are in inch and then measure there wrist to elbow
65 would be how tall they are and 9 will be from there wrist to elbow
Did you get a value for the slope?
Y - 9 = 1 ( x - 65)
I cranked out the data on the online linear regression calculator and got the results on the attachment. The slope is approximately 2.1 or 2.1 to 1. http://easycalculation.com/statistics/regression.php
2.1 to 1 means that if the wrist-elbow measure on somebody goes up 1 ", expect the person's height to go up 2.1 inches. I my wrist-elbos measure is one inch more than yours, expect me to be 2.1 inches taller than you.
I am confused
The confusion began when all the parts of the problem were not stated at the outset. The line you have given: Y - 9 = 1 ( x - 65) has slope 1. That line is based on one ordered pair, I assume. I used all the points shown in the upper left corner of your graph to generate an equation for the line showing the relationship between wrist-elbow length and height. At this point, I, too, am confused.
I only needed to find the slope for Point A and Point G
x2 = 66 x1 = 65 y2 = 10 y1 = 9 m = 10/65 – 9/65 = 1 Y - 9 = 1 (x - 65)
