McKenzie; Updated April 24, Parallel lines are straight lines that extend to infinity without touching at any point. This concept is illustrated below.

Estimates the y-intercept by graphing the line using the given point and the slope. However, what about the slope? So, if we know the slope of the line parallel to our line, we have it made.

Show Solution To answer this we will first need to write down the equation of the line. When writing an equation of a line, keep in mind that you ALWAYS need two pieces of information when you go to write an equation: Okay, we now need to move into the actual topic of this section.

A line is parallel to another if their slopes are identical. In algebra, when you study slope, essentially what you are dealing with is angles.

GO Parallel and Perpendicular Lines Now that we have a better understanding of lines and angleswe are ready to begin applying some of these concepts onto the Caresian coordinate plane. Both sets of lines are important for many geometric proofs, so it is important to recognize them graphically and algebraically.

If we do some more evaluations and plot all the points we get the following sketch. What is the slope of a vertical line? So, if we know the slope of the line parallel to our line, we have it made.

If you need more of a review on how to use this form, feel free to go to Tutorial Note that -1 is the y value of the ordered pair given. At this point all that we need to worry about is notational issues and how they can be used to give the equation of a curve.

If you need a review on horizontal lines, feel free to go to Tutorial What is the slope of line k? The second equation, however, needs to be manipulated. Even the best athletes and musicians had help along the way and lots of practice, practice, practice, to get good at their sport or instrument.

Note that 2 is the x value of the ordered pair given. We now have the following sketch with all these points and vectors on it. Write an equation of the line that has an undefined slope and passes through 2, 3.

Provide the student with several examples of equations written in standard form or point-slope and ask the student to rewrite each equation in slope-intercept form and identify its slope as well as the slope of a line parallel to it. Thus, in the coordinate plane, if we want two different lines to never intersect, we simply apply the same slopes to them.

So, before we get into the equations of lines we first need to briefly look at vector functions. If you said any point on the line and the slope you are correct.May 13, · The lines are parallel. so, slopes of the lines are same. So, the line equation is y = 3/4x + c Find the y-intercept value by substituting (-2,-5) in the line ultimedescente.com: Resolved.

Equation of the given parallel line and a point on your line Write the equation of the given line in slope-intercept form to determine its slope, then use that same slope and your point in the point-slope formula. Find the equation of a line that passes through the point (3, 1) and is parallel to the line.

In order to solve this kind of problem, we will need to keep in mind that parallel lines have the same slope. We will also have to utilize what we know about equations in.

You must know the structure of a straight-line equation before you can write equations for parallel or perpendicular lines. The standard form of the equation is "y = mx + b," in which "m" is the slope of the line and "b" is the point where the line crosses the y-axis.

In the last lesson, I showed you how to get the equation of a line given a point and a slope using the formula. Anytime we need to get the equation of a line, we need two things a point a slope.

ALWAYS! So, what do we do if we are just given two points and no slope?

Parallel Lines. Perpendicular Lines. Graphing Linear Inequalities. Writing linear equations using the slope-intercept form. Where m is the slope of the line and b is the y-intercept. You can use this equation to write an equation if you know the slope and the y-intercept.

Example.
