To graph the equation
, rewrite it as
. The slope is 3 and the y-intercept is 1. Plot the point (0,1) and use the slope to find another point, such as (1,4). Draw a straight line through these points to graph the equation.

To graph the equation
, you can first rearrange it into slope-intercept form
. Adding
to both sides gives
. Here, the slope (
) is 3, meaning for every one unit you move right on the x-axis, you go up three units on the y-axis. The y-intercept (
) is 1, putting it at the point (0,1) on the graph.
Now, let’s take a quick detour into the world of intersest intercepts! The points where the line crosses the axes are important. For this equation, the y-intercept occurs when
which gives us (0, 1). For the x-intercept, set
:
leads to
, giving the point
. Plotting these points will help you sketch the line beautifully!
