Find the equation of the straight line if it pass though the points (4,-3) and is parallel to the x-axis?

Since the line is parallel to the x-axis, its equation will be of the form y = k, where k is a constant.

Since the line passes through the point (4, -3), we can substitute these coordinates into the equation to find the value of k:

-3 = k

Therefore, the equation of the straight line passing through the points (4, -3) and parallel to the x-axis is:

y = -3

The equation of a horizontal line is given by:

$$y = b$$

where b is the y-intercept.

Since the line passes through the point (4, -3), the y-intercept is -3. Therefore, the equation of the line is:

$$y = -3$$
