The equation of the horizontal line passing through (4,7) is y=7.

Explanation:

Equation of a horizontal line line is always of the type

y=k

As in the pint (4,7) ordinate is 7

the equation of the horizontal line passing through (4,7) is y=7.

Note - The equation of a vertical line is always of the type x=k and hence the equation of the vertical line passing through (4,7) is x=4.
