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

Since the line is horizontal, the slope is 0.

The equation of a horizontal line passing through a given point (a, b) is y = b.

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

For a horizontal line, the slope is always 0.

Given that the line passes through the point (7,5), we can use the point-slope form of a linear equation to find the equation of the line.

The point-slope form is: y - y₁ = m(x - x₁)

Substituting the values into the equation, we get:

y - 5 = 0(x - 7)

Simplifying, we have:

y - 5 = 0

Therefore, the equation of the horizontal line passing through (7,5) is:

y = 5
