The reason being that you will be able to find the slope of a line in the exact same manner as above if you have the values of any two different coordinates on the line. Slope of the line is -12. Slope calculator is a free online tool used to calculate the slopegradient when coordinates of two points are given.
The formula becomes increasingly useful as the coordinates take on larger values or decimal values.
The distance between both these coordinates are also shown. Slope y₂ - y₁ x₂ - x₁ Notice that the slope of a line is easily calculated by hand using small whole number coordinates. Slope of the line is -12. To find the slope of a linear equation start by rearranging the given equation into slope-intercept form which is y mx b.
