Mathematics
In the coordinate plane, the x axis (y=0) and y axis (x=0) are perpendicular. The product of the slopes of two perpendicular lines is -1. Explain why this definition does not apply to the lines y=0 and x=0.

Ответ:
see the explanation
Step-by-step explanation:
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In the coordinate plane, the x axis (y=0) and y axis (x=0) are perpendicular
however
this definition does not apply to the lines y=0 and x=0.
because
The slope of the horizontal line y=0 is equal to zero and the slope of the vertical line x=0 is undefined
