Day 7

Spaced Revision

Come back to Straight Lines after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • Distance formula finds the length between two points.
  • Section formula gives a point dividing a segment in a given ratio.
  • Midpoint is the equal-ratio case of the section formula.
  • Slope measures steepness of a line.
  • Inclination is measured from the positive x-axis and stays between 0 and 180 degrees.
  • Horizontal line has slope 0.
  • Horizontal lines have equations y = constant.
  • Vertical lines have equations x = constant.
  • x-axis is y = 0 and y-axis is x = 0.

Common Mistakes to Avoid

The slope of a vertical line is infinite, so it can still be used in normal slope formulas.

A horizontal line has no y-intercept and a vertical line has no x-intercept.

The point-slope form y - y1 = m(x - x1) can be used for every line, including vertical lines.
