Answer:
The answer is 9
Step-by-step explanation:
Answer:
Equation of x-axis is y=0, it is a horizontal line.
Step-by-step explanation:
We need to find the equation of the x- axis and type of line it represents (vertical or horizontal ).
On the x-axis, the value of y is always 0 and the value of x can be and real number. Since y is free from x and its value is 0, therefore the equation of x-axis is
Value of y remains same. So, it represents a horizontal line which intersects the y-axis at 0.
Therefore, equation of x-axis is y=0, it is a horizontal line.
