How do you graph y equals 2x minus 2?

Answer 1

There are several ways to graph equations. One is to compile a table of values. For example, calculate how much "y" would be if "x" is 0, 1, and 2. In theory, two values is enough for a linear equation such as this one; the third serves as a check. For example, if x = 0, y = 2(0) -2 = -2, so you have the ordered pair (0, -2). Calculate a few additional ordered pairs, plot them on the graph paper, and draw a line through them. For this particular equation, you should get a straight line.

Answer 2

To graph y = 2x - 2, you can start by plotting the y-intercept at (0, -2). Then use the slope of 2 to determine additional points. For example, if you move one unit to the right, you would move up two units to plot (1, 0). Connect the points to form a straight line.
