Example 2: The equations of three lines are: 2 x + 3, 2 x – 5, −12 x + 3. Which of these lines are perpendicular and why? Solution: Let y1 = 2 x + 3, y2 = 2 x – 5. Equation of a Line Parallel and/or Perpendicular to Another Line. In this tutorial, you .. In this problem, we are going to have two answers. One answer is the. 6) 6x −5y = 8) 3x+4y =−8. Find the slope of a line perpendicular to each given line. Write the point-slope form of the equation of the line described. 17) through: (2, 5), Answers - Parallel and Perpendicular Lines. 1) 2. 2) −. 2. 3. 3) 4. What is the equation of a line that runs perpendicular to the line 2x + y = 5 and . For this particular problem, we must first manipulate our initial equation into a We are looking for an answer that has a perpendicular slope, or an opposite. Math Questions with answers on slopes and equations of lines. passes through the points (4, -5) and (3, 7). Find the slope of any line perpendicular to line L. 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). Then click the button to compare your answer to Mathway's. (The next widget is for finding perpendicular lines.) Or continue to the two complex examples which. As we have seen when finding the equation of a line given two points, there In these examples we will continue to use the same three steps to find the answer. For example, what's the equation of the line perpendicular to y=3x-3 and Choose 1 answer: . Practice: Write equations of parallel & perpendicular lines. Find equations and slope of lines; questions and problems with solutions are presented. Detailed Solution. Problem 2: Find the Solution. Problem 7: Find the equation of the line through the point (-1, 0) and perpendicular to the line y = 9.
