Document Summary
I - equation of a line: the equation. The equation of a line is the following: y = mx + b. M is the slope of the line. Which is the same as (point-slope form of the equation): With this, if you know the slope of the line, and one point on this same line, we just have to plug them in this equation, and we get the equation of the line: special lines. A horizontal line can be expressed but the equation y = b. In this equation, b is the y- interecept of the line. A vertical line can be expressed but the equation x = a. In this equation, a is the x- interecept of the line. Now, let"s recall the equation of the slope: Parallel lines are two lines that are always the same distant apart. To check if two lines are parallel, we have to check if they have the same slope.
