Well, it's perpendicular to A, so it's going to be the negative inverse of this. So its slope, the negative inverse of two-fifths, the inverse of two-fifths is five. So if we can find the slope ofwe will have the information we need to proceed with the problem.

You are not going to get off that easily. If you need a review on vertical lines, feel free to go to Tutorial When a problem asks you to write the equation of a line, you will be given certain information to help you write the equation. If you need help rewriting the equation, click here for practice link to linear equations slope.

We know that y is equal to negative 7 when x is equal to 6. We know we are looking for a line parallel to. Next we are going to work with b. Now, why is it called point-slope form?

If a line has a slope of 5, what is the slope of a line parallel and a line perpendicular? Pat yourself on the back if you said 0. Your slope is the coefficient of your x term.

To understand why, go to this interactive tutorial. Most students, since they have already labeled a and when finding the slope, choose to keep that labeling system. 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: You would first find the slope of the given line, but you would then use the negative reciprocal in the point-slope form.

Now substitute those values into the point-slope form of a line. If you said any point on the line and the slope, you are correct. A review of the main results concerning lines and slopes and then examples with detailed solutions are presented.

So the slope of A is 2. The equation of a line is given by.

You can just do a little bit of algebra. So let's work out what b must be-- or what b, the y-intercept, this is a lowercase b, not the line B. So what we'll do is figure out the slope of A, then take the negative inverse of it.

Let me do it in a better color. Connect these three points and label to graph it correctly. Both forms involve strategies used in solving linear equations.

Add eight to negative five.

So very quickly, you could use this information and your knowledge of point-slope form to write this in this form. Look at the slope-intercept and general forms of lines.

And we know this is the slope between these two points. Two non vertical lines are parallel if and only if their slopes are equal. So this is going to be y minus my little orange b.

You swap the five and the two, you get five halves. You can take the slope-intercept form and change it to general form in the following way.You may already be familiar with the "y=mx+b" form (called the slope-intercept form of the equation of a line).

It is the same equation, in a different form! The "b" value (called the y-intercept) is where the line crosses the y-axis. Converting 2x-y=7 into a slope-intercept form: y = 2x+7 The slope of 2x-y=7 is 2 So the slope of the required line is -1/2 (the slopes of perpendicular lines are the negative inverse of each other) We are looking for a line with slope m=-1/2 which passes through (x_1,y_1)=(8,5) In slope-point form this is (y-5)=(-1/2)(x-8) Converting to slope intercept form: y =-1/2x+9 and in standard form.

Write the equation in slope-intercept form. Identify the slope and y-intercept. SHOW ALL WORK - Write the equation of a line that is perpendicular to the given line and that passes through the given point.

> equation of the line in slope-intercept form. so. 5/5(7). The notion of line or straight line was introduced by ancient mathematicians to represent straight objects (i.e., having no curvature) with negligible width and librariavagalume.com are an idealization of such objects.

Until the 17th century, lines were defined in this manner: "The [straight or curved] line is the first species of quantity, which has only one dimension, namely length, without any width. After completing this tutorial, you should be able to: Find the slope of a line that is parallel to a given line.

Find the slope of a line that is perpendicular to a given line.

To find the equation of the line perpendicular to the given line, x + 7y = 8, you need two important pieces of information, i.e., 1.) you need to know the coordinates (x, y) of a point that the perpendicular line passes through, and 2.) the slope of the perpendicular line.
