Find the standard form of the equation of the circle whose center and radius are given below. (h,k)=(2,−4); r=3. Standard Form of the Equation of a Circle: Let (x,y) be a point on a circle. Since a circle is a collection of points eq...
Example 6 The center of a circle has coordinates (1, 2). The point (3, -1) lies on this circle. Find the slope of the tangent line at (3, -1). Example 7 Example 8 Example 9 Example 10 Congruent Tangents Theorem Tangent segments from a common external point are congruent. ...
A parabola is defined as being a curve in which any point is equidistant from a fixed point called the focus and a fixed straight line called the directrix. Practically, a parabola looks like this: A parabola Every parabola behaves in a similar way. If it is upward opening, it will have...
One of the points may have a precision associated with it. If this is the case then I draw a circle around the point with the radius set to the precision value. Again this works fine however my bounds checking is now not doing what I want it to do. I want to ha...
What is Midpoint? A midpoint is a point lying between two points and is in the middle of thelinejoining the two points. If a line is drawn joining the two points, then the midpoint is a point at the middle of the line and is equidistant from the two points. Given any two points...
Find an equation of the line that passes through (1, -8) and parallel to the line x + 2y = 6. Explain how to find the equation of a line that is parallel to y = 9 and passes through the point (3,-8). Find the equation of the line that passes through (7,-2) and is paral...
