find the parametric equations of the line that passes through the point p(2,3,4)& parallel to the xz-plane

To be parallel to the xz plane, y must be constant. In this case, the constant is y = 3.

There is more than one line parallel to the xz plane that passes through that point. If the z vs x slopes of the various possible slopes in the y=3 plane are denoted by m,

z - 4 = m (x - 2)

To find the parametric equations of a line passing through a point and parallel to the xz-plane, we can set the y-coordinate to be constant.

Let's assume the y-coordinate of the given point is y₀.

In this case, the given point is p(2, 3, 4), so y₀ = 3.

The parametric equations of the line are:

x = x₀ + at
y = y₀
z = z₀ + bt

Since the line is parallel to the xz-plane, the slope of the line in the y-direction is zero, so there is no change in the y-coordinate.

Thus, the parametric equations of the line passing through p(2, 3, 4) and parallel to the xz-plane are:

x = 2 + at
y = 3
z = 4 + bt

where "a" and "b" are any real numbers.

To find the parametric equations of a line parallel to the xz-plane and passing through a given point, we need to consider that the x-coordinate remains constant while the y and z coordinates can vary.

Given that the point P is (2, 3, 4), we can write the parametric equations as follows:

x(t) = 2
y(t) = y₀ (any constant value)
z(t) = z₀ (any constant value)

Since the line is parallel to the xz-plane, we can ignore any change in the y-coordinate. Therefore, we can set y₀ = 3, the y-coordinate of point P.

So, the parametric equations of the line passing through point P and parallel to the xz-plane are:

x(t) = 2
y(t) = 3
z(t) = z₀ (any constant value)

Here, t is the parameter, and z₀ can take any constant value. This will give you a line parallel to the xz-plane passing through point P(2, 3, 4).
