To find the equation of the circle that touches the y-axis at a distance of 4 units from the origin and cuts an intercept of 6 units along the positive direction of the x-axis, we can follow these steps: ### Step 1: Identify the center of the circle Since the circle touches the y-axis at a distance of 4 units from the origin, the center of the circle must be at (4, k) where k is the y-coordinate of the center. The distance of the center from the y-axis is equal to the radius of the circle. ### Step 2: Determine the radius The circle cuts an intercept of 6 units along the positive direction of the x-axis. This means that the circle intersects the x-axis at two points: one at (0, 0) and another at (6, 0). The radius of the circle can be determined by the distance from the center (4, k) to the x-axis. ...
