The slope of a horizontal line is 0. The equation of the horizontal line passing through (7,5) is

The equation of a horizontal line passing through the point (7,5) can be written as:

y = 5

Since the slope of a horizontal line is 0, the equation does not involve x and is of the form y = constant. In this case, the constant is 5, which means that the line passes through all points with a y-coordinate of 5.

Since the slope of a horizontal line is 0, the equation of the line passing through the point (7,5) can be written in the form y = b, where b is the y-intercept.

Given that the line passes through the point (7,5), we know that the y-coordinate of the point will be equal to b. So, b = 5.

Therefore, the equation of the horizontal line passing through (7,5) is y = 5.
