Study Notes
Writing Linear Equations
- Given a point and a slope, use the point-slope formula to find the equation of a line. The formula is y - y₁ = m(x - x₁), where (x₁, y₁) is the given point and m is the slope.
- Ensure to distribute and solve for y to put the equation in slope-intercept form (y = mx + b).
Writing Linear Equations
- Given two points, use the slope formula (m = (y₂ - y₁)/(x₂ - x₁)) to find the slope between the two points.
- Then, use the point-slope formula (y - y₁ = m(x - x₁)) to find the equation of the line.
- Transform the equation into the slope-intercept form (y = mx + b).
Parallel and Perpendicular Lines
- Parallel lines have the same slope.
- Perpendicular lines have negative reciprocal slopes. The product of their slopes is -1.
Negative Reciprocals
- To find the negative reciprocal of a slope, flip the fraction and change the sign.
Determining if Lines are Parallel or Perpendicular
- If the slopes of two lines are equal, the lines are parallel.
- If the product of the slopes of two lines is -1, the lines are perpendicular.
- If neither of the above conditions is met, the lines are neither parallel nor perpendicular.
