The direct variation between the total cost c and the number of gallons g of the gas may be expressed as the following,
c = kg
where k is the constant of variation. In this item, it is the cost of gasoline per gallon which is $1.89. Thus, the final variation equation is,
c = 1.89g

Answer:
Equation of the line; y=x+3
Step-by-step explanation:
Graph the line that passes through the points (5,8) and (3,6) and determine the equation of the line.
Equation of a line: y=mx +b
Let's find the slope:
8-6/ 5-3= 2/2 = 1
y=x+b
Substitute the points in.
y= 8
x = 5
8 = 5+b
b= 3
The y-intercept is 3.
y=x+3
Points on the line: (-2,1) (-1,2) (0,3) (1,4) (2,5)
