The slope is 2 and the y intercept is 4
Are perpendicular.
Are perpendicular to one another.
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.
Yes, they're parallel lines. Both slopes are 2.
[ y = 2x + 4 ] represents a single line, with slope = 2 and y-intercept = 4.
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.
negative reciprocal slopes ---> the lines are perpendicular equal slopes ---> the lines are parallel
They are perpendicular lines because the slopes are 3/4 and -4/3 respectively.
The slopes of two parallel lines will be the same.
The slopes of parallel lines are by definition equal.
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
Take any two lines and look at their slopes. -- If the slopes are equal, then the lines are parallel. -- If the product of the slopes is -1, then the lines are perpendicular.
