The price of a math textbook can be modeled by the equation y=2x + 76 where x is time in years and y is the price of the textbook. This equation tells us that the textbook originally cost $76 and each year the cost went up $2. How many years will it take for the textbook to cost $100

50.6

step-by-step explanation:

y > 1/3x

y < = -x + 4

hope this : )

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
