Finding the Equation of a Line Through and
To find the equation of a line containing the points and , apply the two-points procedure and write the result in slope-intercept form. Step — Find the slope. Apply the slope formula: Subtracting a negative is equivalent to addition: Step — Choose one point. Use , so and . Step — Substitute into the point-slope form : Simplify the left side and distribute the slope on the right: Step — Write in slope-intercept form by subtracting from both sides: The equation of the line is .
