Answer 1

An equation is formed of two equal expressions. The correct option is C.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The equation of the graph that Edwin graphs can be written as,

slope, m = (7-0)/(2-0) = 3.5

c = 0

The equation of the graph that Edwin graphs is p=3.5g.

The equation for the amount Sam spends on milk is given as p=3.4g.

Comparing the two equations the cost of milk per gallon for Edwin is $3.50, while the cost of milk per gallon for Sam is $3.40.

Hence, the correct option is C.
