Two years later, a father will be \( 8 \mathrm{yr} \) more than three times the age of his son. Taking the present ages of father and son as \( x \) and y respectively, write a linear equation for the above and draw its graph. From the graph, find the age of the father, when the sons age is \( 10 \mathrm{yr} \).
