The point at which these two number lines intersect each other is known as the point of intersection which is also known as the origin. It is denoted by the letter O, which is used as a fixed point of reference for the geometry of the surrounding plane. The coordinates of the origin are denoted by (0, 0). It means that at origin, x=0 and y=0.
Solution method 1: The visual approach. We can imagine a rectangle that has one vertex at the origin and the opposite vertex at A . A rotation by 90 ∘ is like tipping the rectangle on its side: Now we see that the image of A ( 3, 4) under the rotation is A ′ ( − 4, 3) . Notice it's easier to rotate the points that lie on the axes, and ...

Jan 14, 2024 · Example 1: Determine the distance of the point (3, 4) from the origin in a Cartesian Plane. Solution: Using the formula d = sqrt (x² + y²), the distance ‘d’ = sqrt (3² + 4²) = 5 units. Example 2: Write the equation of a line passing through the origin and having a slope ‘m’ of 2.
Nov 16, 2022 · A graph is said to be symmetric about the origin if whenever (a,b) ( a, b) is on the graph then so is (−a,−b) ( − a, − b). Here is a sketch of a graph that is symmetric about the origin. Note that most graphs don’t have any kind of symmetry. Also, it is possible for a graph to have more than one kind of symmetry.
