Equation of a line through two points
Questions at easy, medium and hard levels. Pick a level and get a fresh set every time, with instant feedback.
Learn it First find the slope from the two points, then use either point to find b.
Example: Through (1, 3) and (3, 11).
- $m = \frac{11 - 3}{3 - 1} = 4$.
- $3 = 4(1) + b$, so $b = -1$.
- $y = 4x - 1$.
