What is the slope of the line that passes through the pair of points
(1,7),(10,1)

A. 3/2
B. -2/3
C. -3/2
D. 2/3

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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.

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones
