Pre-work
Prework Question
What is the slope and y-intercept of the pre-image?
Case 1: Dilation centered around the origin.
Case 1 Question 1
What happened to the slope? What happened to the y-intercept?
Case 1 Question 2
WITHOUT USING THE GEOGEBRA GRAPH (we will know if you are lying to us. We always know), what would you expect the equation of the line y = 2x + 3 to be after a dilation centered at the origin with a scale factor of 3?
Case 2: Dilation centered on the line
Case 2 Question 1
What happened to the slope? What happened to the y-intercept?
Case 2 Question 2
WITHOUT USING THE GEOGEBRA GRAPH (we will know if you are lying to us. We always know), what would you expect the equation of the line y = 2x + 3 to be after a dilation centered on the line with a scale factor of 3?
Case 3: Dilation not centered on the origin or line
Case 3 Question 1
What happened to the slope? What happened to the y-intercept?
Case 3 Question 2
WITHOUT USING THE GEOGEBRA GRAPH (we will know if you are lying to us. We always know), what would you expect the equation of the line y = 2x + 3 to be after a dilation centered at point (1,3) with a scale factor of 3?
