How do you figure out the slope without drawing the graph? I kinda forgot. I have a chart with data, and I need to know the slope
please help
thank you
slope is the change in y divided by the change in x
Pick two data points
(x1,y1) (x2, y2)
slope= (y2-y1)/(x2-x1)
ysub2-ysub1
------------= slope
xsub2-xsub1
the points are (x,y), obviously. just fill it in.
yes, that's what i meant. i meant to pick two points, not just one.
To calculate the slope without drawing the graph, you can use the formula for slope, which is:
Slope = (change in y)/(change in x)
To determine the change in y, subtract the y-coordinates of two points on the line. Similarly, determine the change in x by subtracting the x-coordinates of the same two points.
For example, let's say you have the following data:
x | y
-------
1 | 3
2 | 6
3 | 9
To find the slope between points (1, 3) and (2, 6), you would calculate:
Change in y = 6 - 3 = 3
Change in x = 2 - 1 = 1
Now, divide the change in y by the change in x:
Slope = (change in y)/(change in x) = 3/1 = 3
So, the slope of the line connecting these two points is 3.
