en.wikipedia.org/wiki/Linear_equation

A linear equation is an algebraic equation in which each term is either a constant
or the product .... It may be helpful to think about this in terms of **y** = **b** + **mx**; where
the line passes through the point (0, **b**) and extends to the left and right at a ...

**y** = **mx** + **b**. We just figured out that a line with a slope of 3 and a **y**-intercept of 2
has the equation **y** = 3x + 2. What if we want to know the equation for this line?

Equation of a Straight Line. The equation of a straight line is usually written this
way: **y** = **mx** + **b**. (or "**y** = **mx** + c" in the UK see below) ...

Every straight line can be represented by an equation: **y** = **mx** + **b**. The
coordinates of every point on the line will solve the equation if you substitute
them in the ...

Slope-intercept form, **y**=**mx**+**b**, of linear equations, emphasizes the slope and the
**y**-intercept of the line. Watch this video to learn more about it and see some ...

points on the graph of **y** = **mx** + **b**. Then y1. = mx1. + **b** and y2. = mx2. + **b**. Use
algebra to simplify y2 – y1 x2 – x1. And give a geometric interpretation. Try this!

This form is my favorite because, if you know what the pieces are, it's SUPER
easy to graph! Here are the pieces: **y** = **mx** + **b**, the slope is m and the **y**-intercept
is.
