What is the slope of a nonverticle line?
To find the slope of a non-vertical line you need two points on the line. Subtract the second y-value from the first y-value, and subtract the second x-value from the first x-value, then divide the first number calculated by the second number calculated. As a formula, it looks like this: slope = (first yvalue - second yvalue) / (first xvalue - second xvalue) Alternatively, if you know calculus, the slope at some x-coordinate a of the function f(x) = d/dx[f(x)] evaluated at a = f'(a).
Can you give an example of collinear point?
As defined by Math Open Reference: collinear points are points that lie on the same line. Any series of points with a yvalue of 4, for example, will be collinear since they lie on the same line. Lines formed by collinear points can have any slope and be located anywhere on a co-ordinate plane. The Math Open Reference link shows a working visual example of collinear points.
What is a central idea of a character of a happy life by sir Henry wotton?
