Ответ:
9m = 6.48
Divide both sides by 9:
m = 0.72
19m = 13.68
Divide both sides by 19:
m = 0.72
So a one minute call costs 72 cents. We can now set up an equation like this:
c = 0.72m

Step-by-step explanation:
The slope goes up one over three. if u need a whole equation then it would be y=1/3x
if you need a slope intercept equation then it would be y=1/3x-4.
