# How do you write an equation in slope intercept form for a perpendicular line

A general formula for finding the slope of a perpendicular line segment will be developed and used. The angle of rotation is 90 degrees because a perpendicular line intersects the original line at 90 degrees.

That the 'm', and multiplies the x. So the slope of A is 2. Use Geometer's Sketchpad to compute the slopes of the following points and find the slope of a line parallel and the slope of a line perpendicular to the given line.

Write the equation of the line that passes through -6, 4 and is perpendicular to the given line. To do this, we notice that the vertical distance rise between these points is 4 and the horizontal distance run is 2.

Re-writing into point-slope form: Find the slopes of each line segment. Compute the slope of the following lines. This makes sense, given what we know about slope. Ok, so what is the slope. Now, that only leaves the undefined slope. I have to think of the slope as a fraction, remember, rise over run. Its negative reciprocal would then be. Find the slope and y-intercept of the following lines. When is a Slope 0 or Undefined. That's because the slope of a graph determines how much 'y' changes as a function of 'x'.

Check out a similar method of graphing lines, the point-slope format. Even if you only want to check one of them, that would be great. So what we'll do is figure out the slope of A, then take the negative inverse of it. Write an equation in MATH How do I write one equations in slope-intercept form, and three other lines in slope-intercept form that are perpendicular to the first line?.

This is the reciprocal, and differs in sign. Now we can see what an undefined or vertical slope means. These lines go down or "decrease" An easier way to write the slope formula is: When counting UP, that is a positive number.

Investigate the slopes above. Sometimes it will look more complicated. You have a positive slope. But we know that y is always equal to 1. The slope of A is right there, it's the 2, mx plus b. Write the standard form of the equation of each line given the slipe and y-intercept. We know that y is equal to negative 7 when x is equal to 6. If a line has a slope of 5, what is the slope of a line parallel and a line perpendicular. Write the equation for the line in slope-intercept form: If it's almost vertical, but not quite, then it will have a very big steep slope, but not undefined.

Site Navigation Slope of Parallel and Perpendicular Lines In this lesson, the slope of a line segment connecting two points will be compared to the slope of segments parallel and perpendicular.

The slope-intercept form is, where is the slope and is the y-intercept. Using the slope-intercept form, the slope is. The equation of a perpendicular line to must have a slope that is the negative reciprocal of the original slope.

Passes through (6, -5), perpendicluar to the line whose equation is 3x - 1/5 y = 3. Write an equation in slope-intercept form for the line that satisfies each set of conditions. Write the slope intercept form the equations of the lines through the given point parallel to the given line and (B) perpendicular to given line.

point slope ((7,-2) m= 1/2 Algebra Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation. Aug 29,  · Parallel lines share the same slope, so all you have to do is use the equation from that line to get the slope for your first line.

Use algebra to arrange the line’s equation into slope-intercept form which is y = mx + b%(23). How do you write Equation of a line that goes through (8,5) and is perpendicular to 2x-y=7 in slope intercept form and standard form?

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.
