Creating 3 Lines to form Right Triangle

Directions: Using the integers -9 to 9 at most one time fill in the boxes to create a right triangle on the coordinate plane.

Hint

Get creative with the slopes (it’s okay to use unsimplified fractions!). Also, a negative value in the numerator OR denominator of a fraction will create a negative, decreasing slope. A negative value in the numerator AND denominator makes the fraction positive (negative/negative=positive).

Answer

Many answers. One answer is y=2/1x+3, y= -4/8x+5, y= -6/4x+9
