straight lines

What makes a line straight?
Parallel straight lines have the same slope and are the same distance apart, so they will never intersect. Perpendicular straight lines cross each other and form four perfect right angles in the process. Slanted or oblique straight lines are just as they sound: they are straight lines at an angle.

Is straight lines important for JEE?
Straight Lines JEE is the foundation of Coordinate Geometry. Coordinate Geometry is that part of JEE Mathematics which almost covers 20% weightage ofJEE Advanced Mathematics Paper. This tells us how important Straight Lines JEE is.

What are straight lines in math?
Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis). ... The above graph has equation y = (4/3)x - 2 (which is the same as 3y + 6 = 4x).

What is difference between line and straight line?
line can be straight or curved. The word line usually means a straight line. Astraight line is the shortest distance between two points. A straight line is the linetraced by a point moving in a direction that does not change.

What is line explain?
Line (actually a straight line), together with point, is a basic concept of elementary geometry. The idea of line is an abstraction that distills our intuition that a straightline is the shortest way between two points. ... The point of intersection lies on (or belongs to) both lines. Parallel lines have no common points.

What is the 11th dimension?
The 11th dimension is a characteristic of space-time that has been proposed as a possible answer to questions that arise in superstring theory. ... According to superstring theory, all of the elementary particles in the universe are composed of vibrating, one-dimensional mathematical objects known as strings.

Are straight lines curves?
In mathematics, a curve (also called a curved line in older texts) is, generally speaking, an object similar to a line but that need not be straight. Thus, a curve is a generalization of a line, in that its curvature need not be zero.
