# How to solve perpendicular and parallel equations

To find the slope of the given line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = –10 is m = 4/5. Therefore, the slope of the line perpendicular to this line would have to be m = –5/4. Step 2: Use the slope to find the y-intercept. 17 Jul - 12 min - Uploaded by The Organic Chemistry Tutor This algebra video tutorial shows you how to write the equation of a line that is parallel and. 12 Jun - 3 min Sal determines which pairs out of a few given linear equations are perpendicular. Practice.

12 Jun - 3 min Given line A and point P, Sal finds the equation of the line perpendicular to A that passes. Two parallel lines won't ever intersect. Horizontal and vertical lines are perpendicular to each other i.e. the axes of the How to solve linear equations. Purplemath. There is one other consideration for straight-line equations: finding parallel and perpendicular lines. Here is a common format for exercises on this.

Example: Find the equation of the line that is: parallel to y = 2x + 1; and passes though the point (5,4). The slope of y=2x+1 is: 2. The parallel line needs to have. Parallel Lines; Perpendicular Lines; Problem Solving What is the equation of the line that is parallel to the line 2x−3y−8=0 and passes through the point (3,5)?. You must know the structure of a straight-line equation before you can write equations for parallel or perpendicular lines. The standard form of. Given a point and a line perpendicular to or parallel to the unknown line, write the equation of the unknown line. Introduction. When you graph two or more linear. bullet Questions Asking Directly for Equations of Parallel or Perpendicular Lines: Solution: The slope of the given line, y = -4x + 5 is -4 (remember y = mx + b).

What line is perpendicular to x + 3y = 6 and travels through point (1,5)? First, put the equation of the line given into slope-intercept form by solving for y. Write the Equation of a Line Parallel to a line and through a point Related Links : Worksheet on this topic · parallel and perpendicular lines. Students are often. If we know the equation of a line, we can use what we know about slope to write the equation of a line that is either parallel or perpendicular to the given line. Improve your math knowledge with free questions in "Write an equation for a parallel or perpendicular line" and thousands of other math skills.

Determining the slope of a perpendicular line can be performed mentally. Some examples . Finding Equations of Parallel and Perpendicular Lines. We have. Parallel lines are a fixed distance apart and will never meet, no matter how long To find the equation of a perpendicular line, first find the gradient of the line. Equations of Parallel Lines. You can easily calculate a line that is parallel to the line with a know equation. Let us look at the example underneath. The equation. Equation of a Line Parallel and/or Perpendicular to Another Line To be successful in solving this kind of problem, you need to have some background.
