Answer:

See explanation.

Explanation:

#2x+3y=9#
#3y=9-2x#
#y=(9+2x)/3#

From the type of equation we see that the function will be a straight line that does not pass from the #(0,0)# point.

You then insert #2# random values for #x# #(x_1# and #x_2)# and get 2 values for #y# #(y_1# and #y_2)#

So you have #2# coordinates #(x_1,y_1), (x_2,y_2)#. You mark them as points and draw a straight line that passes through both points.
