A  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point is an exact position or location on a plane surface.

The path traced out by a moving point under certain conditions is called the  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point.

When a point moves in accordance with a geometrical law, its path is called  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point.

The  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point of a straight line is the angle, say θ, made by the line with the x-axis
measured in the counter clockwise (positive) direction.

The  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point of a straight line is a number that measures its “direction and steepness”.

In a plane three or more points are said to be  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point if they lie on a same straight line.

The  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point of a line is the point at which the line crosses either the x-axis or the y-axis.

y = m x + b called the  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point form of a straight line because m is the slope and b is the y-intercept.

Two straight lines in a plane would either be parallel or  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point or intersect.

Normally when two straight lines intersect, they form two angles at the  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point.

Lines in the same plane that do not intersect are called  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point.

If these two lines are  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point, then the angle between lines is zero or π.

y − y₁ = m(x − x₁) is callled  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point form of a line.

m = (y₂ − y₁)/(x₂ − x₁) is callled  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point form of a line.

x/a + y/b = 1 is callled  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point of a line.

x cos α + y sin α = p is callled  angle of inclinationcoincidecollinearinterceptintercept formlocuslocus of that pointnornal formparallelparallel linespointPoint - Slopepoint of intersectionslopeslope-intercepttwo point of a line.
