Division by 0 is not defined so 3x cannot be zero. That is, x cannot be zero.
Establish the domain of the graph and select a number of values of x in the range. Calculate y for each of these values.
Mark the x and y coordinates on the Cartesian plane and then join these together by a smooth curve. However, ensure that the curve does not join points on either side of x = 0 (for example x = 1- and x = +1).

What happen to the graph of the line y equals 3x-2 when the equation is changed to y equals 3x plus 6?
The starting point on the y-axis changes from -2 to 6.
What is the graph of 3x plus 2y equals 13?
3x + 2y = 13Subtract 3x from each side:2y = -3x + 13Divide each side by 2:y = (-3/2)x + (13/2)The graph is a straight line, with a slope of (-3/2),through the point (0, 13/2) .
The graph of 3x plus 4y-4 equals 0 crosses the line y equals -2 at what value of x?
3x + 4y - 4 = 0 y = -2 3x + 4(-2) - 4 = 0 3x - 8 - 4 = 0 3x = 12 x = 4 (4,-2)
Which is easier to graph 3x 4y equals 8 or y equals -0.75x plus 2?
They are the same equation just written differently so they are both easy to graph.
Describes the graph of the equations 2y equals 3x plus 2 and 4y equals 6x plus 1?
The lines are parallel.
