ANSWER

y = 3x - 3

EXPLANATION

Let

y = mx + c

be the equation.

We can choose any two ordered pairs to determine the equation of the relation.

(6,15) \: and \:  (8,21)

We find m using the formula;

m =  \frac{y_2-y_1}{x_2-x_1}

m =  \frac{21 - 15}{8 - 6}  =  \frac{6}{2}  = 3

The equation becomes

y = 3x + c

When x=6, y=15.

This implies that,

15 = 3(6) + c

15= 18 + c

15 - 18= c

c =  -3

The equation of the relation is therefore,

y = 3x -3
