Open Middle: Slope and Points Exercise

Author:: Tim Brzezinski

Topic:: Algebra, Coordinates, Difference and Slope, Geometry, Linear Equations

In each app below, move points A, B, C, and D around (on the right side). Use the given digits 1-9 no more than 1 x each to fill in the boxes so that all four slope statements become true.

When a slope statement becomes true, a "true" sign will appear!
Use the + or - buttons to change the sign of the given slope at any time.
Use the custom SLOPE TRIANGLE TOOL to show the slope triangle for the line between any two points.

Can you create a setup where all four slope statements (on the left) are true?

Create a setup that is entirely different from what you created above. Be sure to position the four points and move number tiles to cause all four statements to become true.

Create a setup that is entirely different from the two setups you created above. Be sure to position the four points and move number tiles to cause all four statements to become true.
