Answer: Substitution Property
Think of "substitute" as in replacement. For example, your substitute teacher is a (<span>temporary) </span>replacement for your current teacher. In this case, we're replacing "m4" with "20 degrees".
The slope between these two lines is -3.
In order to find this, we plug the two points into the slope formula below.
m (slope) = (y2 - y1)/(x2 - x1)
m = (4 - -2)/(2 - 4)
m = 6/-2
m = -3
67,585.06 / 19,200
=3.52
Therefore each unit costs $3.50.
24 students because 0-4 is less than 5
The answer is C. C is not a proportion.
