The general equation of a straight line is y = mx + c, where m is the slope of the line and c is the y-intercept. It is the most common form of the equation of a straight line that is used in geometry. The equation of a straight line can be written in different forms such as...
In this lesson, we will learn how to find the equation of a line when given two points on the line. We will also learn how to determine the equation of a vertical line or a horizontal line given two points on the line. To find the equation of a line when given two points on the ...
To find the gradient of the line take any two points on the line (x1, y1) and (x2, y2). The gradient=change in ychange in x=y2−y1x2−x1 Example 2.1 Find the gradient of the lines given in Figure 2.2(a)–(c) and the equation for the line in each case. Sig...
The equation of a straight line is typically introduced to students in middle school, around 7th or 8th grade. However, the concept becomes more relevant and in-depth in high school, specifically in Algebra I and Geometry courses. Math Domain ...
A problem frequently met in geometry is that of determining whether a given point lies on a given line. To solve this problem analytically, the equation of the line is to be found and then tested by substitution whether the co-ordinates satisfy the equation. Some geometric problems require ...
