The number of miles, m, a car can travel varies directly with the amount of gas, g, in its fuel tank. If k is the constant of variation, which equation represents that
situation?
A)m = g+
B)m = kg
k
C)m
9
Dm =
9
k

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

a.)the line for function b is steeper
