1. The equation y=−4 represents a horizontal line where the value of y is always−4 for any value of x. Analyzing the options: Option (a): parallel to the x-axis Since the value of y remains constant at−4 for all values of x, the line is horizontal, which means it is parallel to the x-axis. This optionRead more

    The equation y=−4 represents a horizontal line where the value of y is always−4 for any value of x.
    Analyzing the options:
    Option (a): parallel to the x-axis Since the value of y remains constant at−4 for all values of x, the line is horizontal, which means it is parallel to the x-axis. This option is correct.
    Option (b): parallel to the y-axis
    A line parallel to the y-axis would have an equation of the form x=constant, not y=−4. Therefore, this option is incorrect.
    Option (c): passes through the origin
    The origin is at (0,0), but the equation y=−4 represents a line where y is always −4, so the line does not pass through the origin. This option is incorrect.
    Option (d): None of these
    Since we have already found the correct option, this is incorrect.
    Conclusion:
    The correct answer is (a) parallel to the x-axis. This question related to Chapter 4 Mathematics Class 9th NCERT. From the Chapter 4 Linear Equation in Two Variables. Give answer according to your understanding.

  2. To solve the equation x - 2y = 4, we will substitute the value of x and y from the given options and check which one satisfies the equation. Checking the options: Option (a): (0, 2) Substitute x = 0 and y = 2 into the equation: 0 -2(2) = 0 - 4 = -4 This does not satisfy the equation x - 2y = 4. So,Read more

    To solve the equation x – 2y = 4, we will substitute the value of x and y from the given options and check which one satisfies the equation.
    Checking the options:
    Option (a): (0, 2) Substitute x = 0 and y = 2 into the equation:
    0 -2(2) = 0 – 4 = -4
    This does not satisfy the equation x – 2y = 4. So, (a) is incorrect.
    Option (b): (4, 0)
    Substitute x = 4 and y = 0 into the equation:
    4 – 2(0) = 4 – 0 = 4
    This satisfies the equation x – 2y = 4. So , (b) is correct.
    Option (c): (2, 0)
    Substitute x = 2 and y = 0 into the equation:
    2−2(0)=2−0=2
    This does not satisfy the equation x−2y=4. So, (c) is incorrect.
    Conclusion:
    The correct solution is (b) (4, 0).

    Understanding the Ordinate of Points on the X-Axis
    In a coordinate plane:
    The abscissa is the x-coordinate of a point (x,y).
    The ordinate is the y-coordinate of a point (x,y).
    Any point on the x-axis has a y-coordinate of 0, meaning its general form is (x,0).
    Conclusion:
    The ordinate (y-coordinate) of all points on the x-axis is always 0.
    The x-coordinate (abscissa) can be any number, but the ordinate remains 0.
    Final Answer: (a) 0.
    This question related to Chapter 3 Mathematics Class 9th NCERT. From the Chapter 3 Coordinate Geometry. Give answer according to your understanding.

    Understanding the Abscissa of Points on the X-Axis
    In a coordinate plane: The abscissa is the x-coordinate of a point (x, y).
    The ordinate is the y-coordinate of a point (x, y).
    Any point on the x-axis has a y-coordinate of 0, meaning its general form is (x, 0).
    Conclusion:
    The x-coordinate (abscissa) can be any number because points on the x-axis extend infinitely in both directions.
    The y-coordinate (ordinate) is always 0 for all points on the x-axis.
    Final Answer: (d) any number.

  5. Determining the Location of the Point (0, -2) A point (x, y) is located based on its coordinates: If x = 0, the point lies on the y-axis. If y = 0, the point lies on the x-axis. If both x and y are nonzero, the point is in a specific quadrant. Given Point: (0, -2) The x- coordinate is 0, meaning theRead more

    Determining the Location of the Point (0, -2)
    A point (x, y) is located based on its coordinates:
    If x = 0, the point lies on the y-axis.
    If y = 0, the point lies on the x-axis.
    If both x and y are nonzero, the point is in a specific quadrant.
    Given Point: (0, -2)
    The x- coordinate is 0, meaning the point lies on the y-axis. 
    The y-coordinate is -2, meaning it is in the negative direction of the y-axis.
    Final Answer: (b) on the negative direction of the y-axis.
