What's the Y-Intercept?

Definition: y-intercept

Summary

  1. y equals 2 times x minus 2 is a line in slope-intercept form
  2. Since 'm' represents slope, 2 must be the slope of our line
  3. The 'b' in our equation is -2
  4. The x-coordinate of the y-intercept is always 0, so the y-intercept is (0,-2)

Notes

    1. y equals 2 times x minus 2 is a line in slope-intercept form
    1. The y-intercept is the point on a line where it crosses the y-axis
    1. This is the definition of the y-intercept
    1. The y-axis the the one going up and down in the graph
    1. The y-intercept always has an x-coordinate of 0
    1. y=mx+b is slope-intercept form
    1. 'b' is the y-intercept
    1. y=mx+b is slope-intercept form
    1. The x-coordinate of the y-intercept is always 0
