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 2.1(b), we have the graph of y = 2x + 3. Take any two ...
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.

Equation of a Line Using Point-Slope Formula from Chapter 1/ Lesson 9 77K The point-slope formula is composed of a specific point of coordinates and a slope indicating a type of change over a given variable, such as distance over time. Identify the use of point...
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 ...
