  • What form do you use to find another linear equation?
    point slope form
  • What is the slope of a parallel line?
    the same
  • What does the m in this equation mean?
    slope
  • What linear equation is that?
    point slope form
  • What kind of linear function has a slope of undefined?
    vertical
  • What does the b in this equation mean?
    y-intercept
  • Explain how to graph. Be specific
    On the x-axis go right 5 make a dot. On the y-axis go down 12 make a dot.
  • What formula is that?
    slope
  • What linear equation is that?
    intercept form
  • Explain how to get 2x+3y=12 into slope intercept form. Be specific
    subtract 2x and then divide every thing by 3. The answer is y=-2x+4
  • What would you do to find the intercepts from this equation? Be specific
    divide by 48
  • Explain how to graph this linear equation. Be specific
    1st plot your yint of 4 then rise up 2 and run right 3
  • What kind of linear function has a slope of zero?
    horizontal
  • What is the slope of a perpendicular line?
    opposite reciprocal
  • What linear equation is that?
    slope intercept form
  • What kind of line is x=10
    vertical (if you said straight you are out of the game)
  • What would happen to the slope of y=2x+3 if was multiplied by 5
    The line would be steeper
  • What kind of line is y=13?
    horizontal (if you said straight you are out of the game)
  • What linear equation is that?
    standard form
  • What would happen to the slope of y=2x+3 if was multiplied by -1
    The line would go down instead of up
