What makes two linear equations either parallel or perpendicular to each other?
Depending on the value of the slope or gradient if its the same then they are parallel if its a reciprocal then they are perpendicular.
How can we tell if two lines are parallel perpendicular or neither just from their equations?
If the slope of the equations are the same then they are parallel If the slope of the equations are minus reciprocal then they are perpendicular If the slope of the equations are different then they are neither
What is the perpendicular from the point 2 4 to the line y equals 2x plus 10 on the Cartesian plane with work shown?
If you mean the perpendicular distance then it is worked out as follows:- Equation: y = 2x+10 Perpendicular slope: -1/2 Perpendicular equation: y-4 = -1/2(x-2) => 2y = -x+10 The two equations intersect at: (-2,6) Perpendicular distance is the square root of: (-2-2)2+(6-4)2 = 4.472 to 3 d.p.
What equations describes a line that is perpendicular to 2x plus 9y equals 9?
Any one of them that has a slope of 9/2 or 4.5
How do you know when two equations will be perpendicular?
When they meet at right angles when plotted on the coordinated grid.
