How do you graph #2x – 2y = 6# by plotting points?

Answer 1

Solving the equation.

We can first solve the equation.

#2x-2y=6# #-2y=6-2x# #2y=2x-6# #y=x-3#.

Now we are ready to plot the points. Every time you select a value for #x# the corresponding value for #y# is #x-3#. So you can select the #x# you want and subtract 3. For example

#(3,0)# #(7,4)# #(9.32, 6,32)# #(-31, -34)#

are all valid points for the plot, because the only constraint is to subtract 3 from #x#.

To graph the equation (2x - 2y = 6) by plotting points, you can first rewrite it in slope-intercept form: (y = x - 3). Then, choose values for (x), calculate the corresponding (y) values using the equation, and plot the points on the coordinate plane.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
