A Cartesian coordinate system (UK: / k ɑː ˈ t iː zj ə n /, US: / k ɑːr ˈ t i ʒ ə n /) in a plane is a coordinate system that specifies each point uniquely by a pair of numerical coordinates, which are the signed distances to the point from two fixed perpendicular oriented lines, measured in the same unit of length.

X and Y-intercept is the distance on the axis from the origin where a line or a curve cuts the coordinate axis of the graph. When a line or curve cuts the x-axis at a point, the distance of this point from the origin is called x-intercept and when that line or curve cuts the y-axis at a point, the distance of this point from the origin is called the y-intercept.

Question 3: For a linear equation y = 2x + 6, find the point where the straight line meets y-axis on the graph. Answer: On y-axis, the x-coordinate of the point is 0. Therefore, we can find the intersection point of y-axis and y = 2x + 6 by simply putting the value of x as 0 and finding the value of y. y = 2(0)+6 = 0 + 6 = 6. So the straight ...

5. ### en.wikipedia.org › wiki › Atan2atan2 - Wikipedia

The quantity atan2(y,x) is the angle measure between the x-axis and a ray from the origin to a point (x, y) anywhere in the Cartesian plane. The signs of x and y are used to determine the quadrant of the result and select the correct branch of the multivalued function Arctan( y / x ) .

6. ### www.cuemath.com › geometry › x-and-y-axisx and y axis in graph - Definition, Equation, Examples - Cuemath

A point can be described in a horizontal way or a vertical way, which can be easily understood using a graph. These horizontal and vertical lines or axis in a graph are the x-axis and y-axis respectively. In this mini-lesson, we will learn about the x-axis and y-axis and what is x and y-axis in geometry along with solving a few examples.

x = 1.5 is the axis of symmetry of the parabola y = x 2 - 3x + 4. 2) Let us consider another example. x = 4y 2 +5y+3. Comparing with the standard form of the quadratic equation, we get a = 4, b = 5, and c = 3. This parabola is horizontal and the axis of symmetry is horizontal too. We know that y = -b/2a is the equation of the axis of symmetry ...
