Slope: Parallel & Perpendicular Lines Purplemath
WebSep 30, 2014 · How do you determine if the two lines are parallel, perpendicular, or neither if line a passes through points (–1, 4) and (2, 6) and line b passes through points (2, –3) and (8, 1)? ... If the slopes are negative reciprocals then the lines are perpendicular. If the slopes are neither of the above are true then the lines are neither. … WebA perpendicular line has a slope of the negative inverse of the original equations slope. If y=2x+1 is the first equation, it has a slope of 2. The negative inverse of 2 is -½ so a perpendicular line would be y= -½x + ? And value can be used for the ? and the line … A nicer green. If this lines slope is negative two-fifths, the equation of the line we … what do you mean the slope of AC is negative, it is going up from left to right … incendie homecourt
Parallel & perpendicular lines intro Analytic geometry (video)
WebLine 1: Line 2: Parallel Lines: The lines are parallel if their slopes are equal or the same. That means. Equal Slopes: Graph: Perpendicular Lines: The lines are perpendicular if their slopes are opposite reciprocals of each other. Or, if we multiply their slopes together, we get a product of - \,1 −1 . WebDec 21, 2024 · You determine if two lines are parallel, perpendicular, or neither based on their slope. If they have the same slope, they are parallel. If the slopes are opposite inverses, they are perpendicular. So, 3/4 and -4/3. If neither of those is true, the lines are neither. You need to set both equations to slope-intercept form: y=mx+b. WebCompare the slope of the perpendicular lines. The slope of the red line: m 1 = − 3 − 1 2 − ( − 2) = − 4 4 = − 1. The slope of the blue line. m 2 = 2 − ( − 2) 3 − ( − 1) = 4 4 = 1. The slopes of two perpendicular lines are negative reciprocals. The product of the slopes of two perpendicular lines is -1 since. m ⋅ − 1 m ... incognito math path
