Refer to the explanation.
Explanation:
Graph:
Rearrange to standard form:
We only need two points to graph a linear equation. With the standard form, we can easily determine the x- and y-intercepts, and then plot them.
X-intercept: value of
Substitute
The x-intercept is
Y-intercept: value of
Substitute
The y-intercept is
Plot the x- and y-intercepts and draw a straight line through the points.
