**definition**of**Y Axis**: The line on a graph that runs vertically (up-down) through zero. It is used as a reference line so you can measure...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 ...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 ) .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**...
