Storyboard Text

  • sure, lets try y>x+2
  • Can you teach me how to graph an inequality?
  • First you graph the y-int at (0,2)
  • next you graph the slope you go up 1 and right one. you can do this as many times as you would like but you really only need to do it once.
  • now you must figure out what type of line it is so since it is greater than it is a dashed line .
  • Finally you you need to figure out what side you are going to shade. How you do this is you pick a test point and plug it in.(0,0) is a good one as long as it is not on the line.  if the test point is true then you would shade on the side with the test point but if it is false then you you would shade the opposite side.
  • no problem
  • thank you for teaching me how to graph a line
