Say that line m is described by the function m(x) and line l by l(x). If m is a reflection of l in the x axis, then it follows that m(x) = -l(x). Try drawing a sketch to satisfy yourself of this. At the intersection(s) of l and m, m(x) = l(x). But we have also stated that m(x) = -l(x). This can only be true if the value of both functions (i.e. the y coordinate, s) is zero.
Perpendicular if they form right angles if not they form vertical opposite equal angles
Orgin is the intersection of horizontal and vertical number lines.
The point of intersection.
point
The coordinates of the point of intersection must satisfy the equations of both lines. So these coordinates represent the simultaneous solution to the two equations that that represent the lines.
If the two lines form an X then each angle directly across from another is congruent or equal to that angle.
No. Glide reflection is a combination of an ordinary reflection and a slide along the line of reflection. A two reflections across two vertical lines is a translation without any reflection or rotation.
It is (6, -1).
When two straight lines intersect they form 360 degees with opposite angles being equal.
All lines of longitude are equal. The longest line of latitude is the Equator.
Vertical equal opposite angles are formed when lines intersect each other.
Vertical equal opposite angles are formed when lines intersect each other.

Perpendicular if they form right angles if not they form vertical opposite equal angles
They are equal opposite vertical angles and if the lines are perpendicular to each other then 90 degree angles are formed.
Orgin is the intersection of horizontal and vertical number lines.
