You can put this solution on YOUR website! It depends on whether it is y = 3/4 or x = 3/4.
.
If it is y = 3/4, then for all values of x, y = 3/4. This is a horizontal line.
.
If it is x = 3/4, then for all values of y, x = 3/4. This is a vertical line.
.
Of course, if it is y = 3/4x, then you have the graph:
