If x=0 and y> 0, where is the point (x, y) located?

Step-by-step explanation:

Look at the picture.

(1) If x = 0, then the point is on the y-axis.

(2) If y > 0, then the point is above the x-axis.

From (1) and (2) we have: The point is on the positive y-axis.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
