Answer:
~28
Step-by-step explanation:
5 feet 3 inches is 5.25 feet.
We divide 7/5.25 which equals 1.3333333333333 (repeating)
That means we multiply 21 by 1.333333333333 which would round up to 28 feet. (the exact answer is 27.99999999999999999)
Positive 2 is your slope, (rise over run) if you have to graph it and -1 is your y-intercept
Replace x with a couple of numbers, solve for Y them mark those points on the graph and connect with a line.
