Pick some values of x say -6, 0 and +6 perhaps, to keep it simple. Find the value of y at each of these and then plot to give a straight line of shape /.
You can put this solution on YOUR website! Make a table choosing values for x and then solve the equation for y;
x |y
----
2|
3|
-2|
Know plug these values in for x;
when x=2;
(2)=6y =y =y
when x=3
(3)=6y =Y =Y
when x=-2;
(-2)=6y =y =y
Hope you understand
