One flight of stairs has a slope of 3/4 , while another flight of stairs contains points (-2,3) and (14, 15). Would these be parallel, perpendicular, or neither?

Perpendicular

Step-by-step explanation:

m=y2-y1/x2-x1

m=15-3/14-(-2)

m=3/4

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
