Using either a stairway or a handicap access ramp (specific data values given), model a linear function and determine if the stairs/ramp are “up to code” based on International Building Codes (stairs) or ADA ramp requirements.

ALGEBRA

Using either a stairway or a handicap access ramp (specific data values given), model a linear function and determine if the stairs/ramp are “up to code” based on International Building Codes (stairs) or ADA ramp requirements. [MO 4.3, MO 4.4, MO 4.6]

Option 1—Stairs

Measure the rise and run of several steps and calculate the equation of the line of the stairs.

Option 2—Ramp

Choose one from each set and post the values to the forum. You must choose a pair of values not already selected by a classmate.
