What is the slope for the following data?
X -1 0 1 2
Y 0 1 2 3
y2 - y1
----------
x2 - x1
rise / run
well, geez. You have the formula. Pick any two (x,y) pairs and plug them in:
(3-0)/(2+1) = 1
You can see just by looking at the table that when x increases by 1, so does y.
You have found the slope.
To find the slope of the given data, we can use the formula:
Slope = (y2 - y1) / (x2 - x1)
Let's plug in the values from the given data:
x1 = -1
y1 = 0
x2 = 2
y2 = 3
Now substituting the values into the formula, we get:
Slope = (3 - 0) / (2 - (-1))
Slope = 3 / 3
Slope = 1
Therefore, the slope for the given data is 1.
