    What is straight lines?

    Straight lines in coordinate geometry are described by slope, intercepts and several standard equation forms.

    Why it matters

    They are the simplest curves and the base case for conics, calculus and graph reading.

    Key concepts you will practise

    • Slope of a line and slope between two points
    • Slope–intercept, point–slope and two-point forms
    • Parallel and perpendicular conditions
    • Distance from a point to a line

    Tips that save marks

    • Perpendicular slopes multiply to −1.
    • Convert to slope–intercept form when comparing two lines.

    Frequently asked questions

    What is the slope of a vertical line?

    It is undefined, because the change in x is zero.

    How do I tell whether two lines are parallel?

    They are parallel when their slopes are equal and their intercepts differ.
