Condition for the line y = mx + c to be a tangent to the circle and finding the point of contact - Formula. Solved Example Problems

How do you proof that y=mx+c touches the circle …

 · What I believe is that the line will only touch the circle when it is at a tangent. Therefore, the point of intersection between of the two lines should mean that it will only cross at one point. Which we should be able to prove when we use the quadratic formula’s discrminant b²-4ac. The only problem is I can’t get the discrimant to equal 0. y=mx+c x²+y²=a² x²+m²x²+2cmx+c²=a² x²

SOLUTION: what does the equation y=mx+c mean?

For y = mx + c, we have y expressed as a function of x, whereby any increase in x is calculated to be an (m times x) increase in y. The c value is the value of y when x = 0. If this function is graphed as a line, m is the slope of that line and c is the y-intercept. Answer by AnlytcPhil (1756) ( Show Source ):

What is the derivative of mx+b? + Example

 · Gió. Dec 21, 2014. Considering the function (linear): y = mx + b where m and b are real numbers, the derivative, y’, of this function (with respect to x) is: y’ = m. This function, y = mx + b, represents, graphically, a straight line and the number m represents the SLOPE of the line (or if you want the inclination of the line).

Equation of a Straight Line
Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis). NB1: If you are given the equation of a straight-line and there is a number before the ‘y’, divide everything by this number to get y by itself, so that you can see what m and c are.
