To solve this problem, let's try to find a point on the line. It appears that (6, 8) is a coordinate on the line. We can substitute this x-value of 6 into the functions and question whether it equals the y-value of 8.


Equation 1:


8 + 2 \stackrel{?}{=} (6)/(5) (6 + 1)


10 \\eq (42)/(5)

The first option choice is not the equation of our line.


Equation 2:


(8 - 2) \stackrel{?}{=} (6)/(5) (6 - 1)


6 = 6 \,\,\checkmark

The second choice is the equation of our line. For more verification, we will check the other equations as well.


Equation 3:


8 + 1 \stackrel{?}{=} (6)/(5) (6 + 2)


9 \\eq (48)/(5)

The third choice is not the equation of our line.


Equation 4:


8 - 1 \stackrel{?}{=} (6)/(5) (6 - 2)


7 \\eq (24)/(5)

The fourth option is not the equation of our line.


The second choice is the equation of the line.
