When the lines intersect at a 90ΒΊ angle
As far as we know, two lines can be perpendicular, or they can be parallel, but they can't be both.
They're parallel if their slopes are equal.

When the lines intersect at a 90ΒΊ angle
As far as we know, two lines can be perpendicular, or they can be parallel, but they can't be both.
Horizontal lines have a slope of zero, and the slope of vertical lines is undefined. Parallel lines have equal slopes, and perpendicular lines have slopes that are negative reciprocals of each other. So we can say that: Two nonvertical lines are parallel if and only if they have the same slope. Two lines are perpendicular if and only if their slopes are negative reciprocals of each other. That is, if the slopes are m1 and m2, then: m1 = - 1/m2 or (m1)(m2) = -1
Perpendicular is when two lines cross and form a right angle, which I hope you know what that is.
3x - y = 5 is the equation of a nonvertical line. Definition: Two nonvertical lines are perpendicular if their slopes are negative reciprocals of each other. So we need to find the slope of the given line, and check which of the other lines have a slope that satisfies the definition. Solve for y. 3x - y = add y and subtract 5 to both sides 3x - 5 = y which yields the slope of 3 Thus, the line that have a slope of -1/3 is the required line.
They're parallel if their slopes are equal.
With the information provided, all that can be said is that the slopes are two different real numbers.
draw two intersecting lines that are not perpendicular
Perpendicular is when two lines cross... Parallel is when two lines never meet.... _____________ _____________ = PARALLEL LINES If they cross they are perpendicular, if they don't, they are parallel.
