A direct variation has a constant slope, i.e. (y/x)= constant.
Both of the given two points give a slope of (y/x)=14/2=28/4=7, so the equation of the function is
y/x=7, or simply
y=7x
Answer:
the third one from the top
Step-by-step explanation:
Catherine walks her dog 5.25 miles because there are 7 days in one week and 3/4 x 7 = 5.25
slope = (6 - 1)/(-2 - 1) = 5/-3 = -5/3
Equation
y - 6 = -5/3 (x + 2)
