One way to determine the slope of a line given its equation is to change the equation to slope-intercept form and then identify the coefficient of the x term. We show how to find the slope from the linear equation. Y m x b Where m is the slope and b is the y-intercept.
The change in is equal to the difference in x-coordinates also called run and the change in is equal to the difference in y-coordinates also called rise.
And for a line this will always be constant. A 3 1 2 3 4 3 2 -3frac 1 2frac 3 4frac 3 2 3 2 1 4 3 2 3. Two isosceles triangles have the same height. 12 is the y intercept b and -1 is the slope m and X is just there because its supposed to be.
