FINDING A LINE EQUATION FROM TWO POINTS! (SLOPE & Y-INT)
On this lesson, you will learn how about finding the equation of a line given two points, finding slope from two points, and finding y-intercept given two points (y=mx+b form). Let's do it!
Let's continue exploring the properties of expressions and equations as we practice and learn how to derive the equation of a line in slope-intercept (y=mx+b) form using two points.

Understand the connections between proportional relationships, lines, and linear equations.
Use similar triangles to explain why the slope m is the same between any two distinct points on a non-vertical line in the coordinate plane; derive the equation y = mx for a line through the origin and the equation y = mx + b for a line intercepting the vertical axis at b.
