To find slope, you first need to use the slope equation: y = mx + b. Slope is found with this equation and can be determined by finding the change in “y” and the change in “x”. Once you have these values, you can plug them into the equation and solve for slope.
Example: What is the slope of the line passing through (3,-12) and (5,7)?
To find the slope of this line we will need to use the slope equation. y=mx+b makes it easy for us because we know that m stands for “movement”, which is what direction or change in “y” or “x”. When you look at the table, it is easy to see that the change in x value is 3 and the change in y value is -4.
Plugging this into our equation, we get: m = (-4)/-3
m = -1/1
m= -1. This means the slope of this line is -1/.
So this is how to find the slope.
