A straight line always has the same slope at whatever point it is measured. To show that in the expression y = mx + c, m is the gradient, we begin with a couple of examples as in Figure 2.1(b) and (c) In Figure

Start with the "point-slope" formula (x1 and y1 are the coordinates of a point on the line):y − y1 = m(x − x1)We can choose any point on the line for x1 and y1, so let's just use point (2,3):y − 3 = m(x − 2)...

A horizontal line is a straight line that is drawn from left to right or right to left and it is parallel to the x-axis in the coordinate plane. A horizontal line has an intercept only on the y-axis and not on the x-axis.
What is the Slope of a Horizontal Line and a Vertical Line? In mathematics, the slope of a straight line has the equation: m=y2−y1x2−x1 Here, the values of x and y are the coordinates of two distinct points on the line: (x1,y1)and(x2,y2). The slope of a line can ...

Since the slope m cannot be found, this is not possible. However, you can still write an equation for the line. The equation of a line with an undefined slope isx = x-coordinate.Notice that the y-coordinates can equal to any real number. ...
