What else can I help you with?
If the product of the slopes of two lines equals negative 1 then the lines?
Are perpendicular.
If the product of the slopes of two lines equals -1 then the lines?
Are perpendicular to one another.
How do you use slope to determine if two lines are perpendicular?
You have to know the slopes of both lines. -- Take the two slopes. -- The lines are perpendicular if (one slope) = -1/(the other slope), or the product of the slopes equals to -1.
Are the lines parallel y equals 2x plus 5 and y equals 2x?
Yes, they're parallel lines. Both slopes are 2.
What are the slopes and y intercepts of the following lines y equals 2x plus 4?
[ y = 2x + 4 ] represents a single line, with slope = 2 and y-intercept = 4.
If two lines are their slopes are negative reciprocals?
If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.If the lines are perpendicular, their slopes are negative reciprocals.
If two lines have slopes that are negative reciprocals of each other then they are if they have slopes that are the same then they are?
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
Are 3x-4y equals -5 and 8x plus 6y equals -5 parallel or perpendicular lines?
They are perpendicular lines because the slopes are 3/4 and -4/3 respectively.
Is x perpendicular?
To determine if two lines represented by the variable ( x ) are perpendicular, we need to know their slopes. Lines are perpendicular if the product of their slopes equals -1. If you have specific coordinates or equations in mind, please provide them for a clear answer.
What kinds of slopes do parallel lines have?
The slopes of parallel lines are by definition equal.
How are the slopes of parallel lines related?
The slopes of two parallel lines will be the same.
What is the difference between slopes of parallel lines and slopes of perpendicular lines?
Slopes of parallel lines have the same slope (they are changing at the same rate).Slopes of perpendicular lines have slopes that are the negative inverse of each other, that is, their product is -1. (The slope of a vertical line is therefore undetermined, not infinity. There is no slope s that times 0 equals -1.)---Let m1 be the slope of line one and m2 be the slope of line two. Then:If the lines are parallel, then their slopes are equal, so m1 - m2 = 0.If the lines are perpendicular, then their slopes are negative inverses of each other, so= m1 - (-1/m1)= m1 + 1/m1= (m12 + 1)/m1
