# How do you graph #y=4x-7#?

There are several ways, but the easiest is probably to start at a point (the y-intercept) and follow the slope.

You know that when x = 0, y = -7 (because y = 4(0)-7 = -7, or you just know the fact that the constant number shows the y-value of the y-intercept). Therefore, you can plot that point on the graph:

Then, let's use the slope of the line in the graph as well. The slope represents the "rise over run", or change in x over change in y. Therefore, if the slope is some number, the y value changes that number of units every time the x increases by one. Using this knowledge, we can simply move over one unit, then move up four units (because the slope is 4), and plot another point:

After plotting only two points, you already have enough information to make the line. Simply draw a line that goes through the two points, and you're done!

(Note that if you continue this pattern - moving right one, up four, and drawing a point - then that point will also be on the line:

To graph the equation y = 4x - 7, you can start by plotting the y-intercept, which is -7 on the y-axis. Then, you can use the slope, which is 4, to find another point. From the y-intercept (-7), move up 4 units and right 1 unit to find another point. Connect the two points with a straight line. This line represents the graph of the equation y = 4x - 7.

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.
