When graphing a line we found one method we could use is to make a table of values. However, if we can identify some properties of the line, we may be able to make a graph much quicker and easier. One such method is finding the slope and the y -intercept of the equation. This formula is known as the slope-intercept equation. If we know the slope and the y -intercept we can easily find the equation that represents the line. We can also find the equation by looking at a graph and finding the slope and y -intercept.

What is the equation of this second line? Parallel lines have the same slope. Solve for the slope in the first line by converting the equation to slope-intercept form. We can set up an equation in slope-intercept form and use these values to solve for the y-intercept. To solve, we will need to find the slope of the line.

There is one other consideration for straight-line equations: finding parallel and perpendicular lines. Here is a common format for exercises on this topic:. I'll first need to find the slope of the reference line. This is just my personal preference. If your preference differs, then use whatever method you like best.
