You can graph any equation using a table of values A A Few Notes about Example 2 This equation, y = 1/2 x 1 has a fraction as the coefficient of x This becomes a little trickier in choosing x coordinates because we could end up with a fraction for the y coordinate This then becomes a little more difficult to graph So, the trick is to look at the denominator of theAnswer (1 of 6) You don't have to 'complete a table of values' You would probably want to do so only if you are new to the absolute value function A table of two points is enough if you know the point of nondifferentiability and one other point, you'll be able to draw the graph y=x12 i(3, 3) NO 6) 3xy=26;
