Directions: Using the digits 1 to 9, at most one time each, place a digit in each box to find the greatest and least possible slope. Source: Dane Ehlert

Directions: Using the digits 1 to 8 [You will use each number only once, except for one number that will be used twice in the same coordinate point. i.e.(1,1), (2,2), (3,3), (4,4), (5,5), (6,6), (7,7) or (8,8)], find three coordinate points that lie on the same line. Write the equation of the line represented by the three points and have …

Directions: Using the digits 1 to 9, at most one time each, place a digit in each box to create a table of values that represent a linear function. Source: Robert Kaplinsky

Directions: Find 3 positive integers that add up to 10. Place each number into one of the blanks to find the largest possible result. Source: Zack Miller (@zmill415)

Directions: Using the integers 0 to 9, at most one time each, 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 …
