These equations are defined for lines in the coordinate system. One form of a linear equation is the slope intercept form which is written ymx b. M Slope or Gradient how steep the line is b value of y when x0.
Enter the linear equation you want to find the slope and y-intercept for into the editor.
Now were going to show another way of expressing linear equations by using the slope-intercept form y mx b. Now we can write a general formula for slope. Does the point -2 -9 lie on the line. If two lines have the same slope the lines are said to be parallel.
