Write the Equation of a Line
Two points in, one equation out. Fourteen tiny steps: find m by walking, then plug one point in and solve for b while the numbers drop into place.
y=mx + bFind m by walking. Then plug one point in and solve for b.
Step 1
Here are the two points
Our job: turn these two dots into one equation.
