Write each rate as a unit rate. 14 hours on 2 weeks

  7 hours/week

Step-by-step explanation:

A "unit rate" is found by dividing one quantity by the other so that the denominator of the result is 1 (a unit). Often, we want the units of the independent variable in the denominator. Sometimes, we don't know what that is, because it depends on the intended use of the rate.

  (14 h)/(2 wk) = 7 h/wk

When numerator and denominator have the same units, the result is a pure number (one with no units). If that number is a fraction, sometimes it is expressed as a percentage; other times, it is left as a fraction or written as a ratio with a colon, such as 1 : 35.

Here, both units are time, so the "unit rate" could be expressed as a fraction. We know there are 168 hours in a week, so this rate could be ...

  (14 hours)/(2·168 hours) = 1/24 . . . . . with no units

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
