The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is [tex]\frac{dy}{dx}[/tex] or:
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Example:
Let's say you're give this table:
x: 1, 2
y: 1, 2
Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1
Do the same for x
Now plug the values taken in the slope formula and you get:
[tex]\frac{2 - 1}{2 - 1}[/tex]
[tex]\frac{1}{1} = 1[/tex]
Therefore the slope is 1.
