First, determine the center of the circle by getting the midpoint of the points given for the circumference. midpoint = ((0 + 0)/2, (3 + -4)/2) midpoint (0, -0.5) Then, we get the radius by determining the distance from either of the circumferential point to the center. radius = √(0 - 0)² + (3 +4)² = 7 The equation for the circle would be, x² + (y + 0.5)² = 7²
The x-intercept looks like (x, 0); the coordinate 0 indicates that the point lies on the x-axis. If we start with 4/5x + 1/3 y= 1 and let y = 0, we will get an equation for the x-intercept:
