First, put the equation of the line given intoslope-intercept form by solving for y. You get y = 2x +5, so theslope is –2. Perpendicular lines haveopposite-reciprocal slopes, so the slope of the line we want tofind is 1/2. Plugging in the point given into the equation y= 1/2x + b and solving for b, we get b = 6..
Simply so, how do you find a perpendicular slope?
To find the slope of the given line weneed 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 ofthe line perpendicular to this line would have to be m =–5/4. Step 2: Use the slope to find they-intercept.
Furthermore, what is perpendicular example? Perpendicular - Definition withExamples Two distinct lines intersecting each other at 90°or a right angle are called perpendicular lines.Example: Here, AB is perpendicular to XY because ABand XY intersect each other at 90°. Non-Example: The twolines are intersecting each other at an acuteangle.
Similarly, how do you find the equation of the perpendicular bisector?
Write an equation into point-slope form, y - k =m(x - h), since the slope of the perpendicular bisector anda point (h, k) the bisector goes through is known. Solve thepoint-slope equation for y to get y = mx + b. Move the kvalue to the right side of the equation.
How do you know if lines are parallel or perpendicular?
If the slopes are the same and the y-interceptsare different, the lines are parallel. If the slopesare different, the lines are not parallel. Unlikeparallel lines, perpendicular lines do intersect.Their intersection forms a right, or 90-degree, angle.
