Then rewrite it in the slope-intercept form. Solution Writing the Equation of a Line Using Two Points The point-slope form of an equation is also useful if we know any two points through which a line passes. Suppose, for example, we know that a line passes through the points (0,...

Point-Slope Form of a Linear Equation Point-Slope Form In most textbooks the graphing form for a linear equation is called Point-Slope Form and is the following: The equation of a line that contains the point (x 1 ,y 1 ) and whose slope is m is: ( ) 1 1 y y m x x − = ...
How do you write an equation in point-slope form? Use the slope (m) of the equation and one known point on the line. Then, put it into this format: (y - the known y coordinate) = m(x - the known x coordinate). For example, if the slope is 3 and the point (-1, 2) is ...
Point-Slope Form Let's look at this mathematically. Let's use what's called point-slope form of an equation. This is going to relate time with my location. To use point-slope form, I need to know a point, such as my starting city, and the slope, such as my speed. For example,...
The meaning of POINT-SLOPE FORM is the equation of a straight line in the form y — y1 = m(x — x1) where m is the slope of the line and (x1, y1) are the coordinates of a given point on the line.
