item 3
andy found three ordered pairs, (0, 250), (5, 575), and (10, 900), for the equation, y = 65x + 250.
when he graphs these, what is the minimum range for the y-axis?
0 to 900
0 to 250
0 to 10
65 to 250

0 to 900

Step-by-step explanation:

The three ordered pairs, (0, 250), (5, 575), and (10, 900) for the equation,

y = 65x + 250

imply that the y-axis should range from 0 to 900. The y-values from the ordered pairs are; 250, 575 and 900

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.
