On a map in the standard (x, y) coordinate plane, the towns of Arlington and Betelwood are represented by
the points (-2,-3) and (-6, -7), respectively. Each unit
on the map represents an actual distance of 10 miles.
Which of the following is closest to the distance, in
miles, between these 2 towns?
A. 128
B. 57
C. 42
D.
E.
28
40

is there more to this question?

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
