How do you find the length of intercept made by a circle on a line?
Solution: Given equation of the circle is x2 + y2 – 4x -6y – 5 = 0. Therefore, length of the x-intercept = 2√g2−c = 2√4−(−5) = 2√9 = 6. The length of the y-intercept = 2√f2−c = 2√9−(−5) = 2√14.

How do you find the parametric equation of a circle?
The equation of a circle in parametric form is given by x=acosθ , y=asinθ
What is the y-intercept formula?
The equation of the line is written in the slope-intercept form, which is: y = mx + b, where m represents the slope and b represents the y-intercept. In our equation, y = − 7 x + 4 , we see that the y-intercept of the line is 4.
How do you find the coordinates of a circle?
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.
How many intercepts can a circle have?
Because a circle is round, it can cross the y-axis twice and have up to two y-intercepts.
How do you calculate the length of a chord?
Where, r is the radius of the circle. c is the angle subtended at the center by the chord. d is the perpendicular distance from the chord to the circle center….Chord Length Formula.

How do you find the intercepts of a circle?
Example: Find the intercepts of the circle for the given equation. To find an x-intercept, let y=0 and solve for x. This equation has one x-intercept. To find a y-intercept, let x=0 and solve for y. A tangent line to a circle may be defined as a line that intersects the circle in a single point.
How do you find the y-intercept of a graph?
A y-intercept is where the graph touches of crosses the y-axis. To find an x-intercept: Let y=0 and solve for x. To find an y-intercept: Let x=0 and solve for y. Example: Find the intercepts of the circle for the given equation.
How to check if a line touches or intersects a circle?
Check if a line touches or intersects a circle 1 Find the perpendicular (say p) between center of circle and given line. 2 Compare this distance p with radius r. More
How do you find the tangent line of a circle?
A tangent line to a circle may be defined as a line that intersects the circle in a single point. This circle is tangent to the x-axis since it is touching the x-axis in a single point. The x-axis (y=0) is the tangent line for the point on the circle (1,0). Example: Find the intercepts of the circle for the given equation.
