How to do you graph #y=4x# by plotting points?
Plug in values for x, solve for y, then pair the corresponding values to find points on the graph.
Plug in values for x, such as -2, -1, 0, 1, 2. The corresponding y-values would be -8, -4, 0, 4, 8, respectively. Pairing these values together would give you the following coordinates: (-2, -8), (-1, -4), (0, 0), (1, 4), (2, 8). Connect these points (preferably using a ruler), and you will obtain the graph of the function in question.

To graph the equation (y = 4x) by plotting points, follow these steps:
-
Choose Values for (x): Select at least two values for (x). It's often helpful to include zero, a positive, and a negative number to get a clear idea of the line's direction. For example, let's use (x = -1), (x = 0), and (x = 1).
-
Calculate Corresponding (y) Values: Use the equation (y = 4x) to find the corresponding (y) values for each chosen (x) value.
- For (x = -1), (y = 4(-1) = -4).
- For (x = 0), (y = 4(0) = 0).
- For (x = 1), (y = 4(1) = 4).
-
Plot the Points: Plot the points on a graph. The points from our example are ((-1, -4)), ((0, 0)), and ((1, 4)).
-
Draw the Line: Connect the points with a straight line. Since (y = 4x) is a linear equation, the points should line up perfectly, and your line will extend infinitely in both directions.
By following these steps, you'll have accurately graphed the equation (y = 4x).

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.
