Writing Linear Equations Using a Given Point and Slope

This activity helps young mathematicians connect the graph and the point-slope form of a line, by first solving a real-world problem and then using that example to motivate the understanding of the equation. By manipulating the gizmo,...

Create a linear equation for a problem when the intercept information is not given. The two-day lesson introduces the class to the point-slope form, which can be used for problems when the initial conditions are not provided. Pupils...

Bridging the knowledge gap between slope-intercept and point-slope forms, Sal explains that the forms are "just two different ways of writing the same equation." This information will be useful to those who have difficulty deciphering...

Given two points on a line, this video shows how to write the linear equation in point-slope, slope-intercept, and standard forms. First, Sal reviews each of these forms, then calculates the slope, writes the equation in point-slope...

Given the coordinates for a point on a line and given the slope of that line, write an equation in point-slope form. Really, all that needs to be done is to use the formula for point-slope form and plug in the values.

Given two points on a line, write an equation in point-slope form. But what's the slope? Oh, you have to figure out the slope first. That can be done given two points. Just use the rise over run slope formula. This isn't so hard after...

Given a table of x and y values, is it possible to write a linear equation from this information? There will be several steps involved. First is to use the point-slope formula to find a slope. Then use that slope and one of the ordered...

Given a linear equation, rewrite it in different forms. No matter what form a linear equation is given in, it can be converted to the other forms. So that means every linear equation can be written in standard form, point-slope form and...
