Lesson 21 Student Summary
The point-slope form of a linear equation is given by m(x2 - x1) = y2 - y1
Given a known (x, y), then the equation is written as m(x - x1) = y - y1
The following is slope-intercept form of a line: y = mx + b
In this equation, m is slope and b is the y-intercept.
To write the equation of a line you must have two points, one point and slope, or a graph of the line.
