Directions: Using the Integers 0-9 (without duplication), provide four sets of points that represent two distinct lines. These lines can be written as two linear equations. Then provide a fifth point that represents the intersection (or solution) of those equations.
Line 1: (__, __) and (__, __)
Line 2: (__, __) and (__, __)
Solution (__, __)
Hint
What is the solution of intersecting lines, what other properties of lines do we need to know
Answer
There are multiple solutions, one example is:
Line 1: (0, 1) and (8, 9)
Line 2: (2, 7) and (6, 3)
Solution (4, 5)
Line 1: (0, 1) and (8, 9)
Line 2: (2, 7) and (6, 3)
Solution (4, 5)
