Slope Calculator — slope and line from two points

ঢাল এবং দুটি বিন্দু দিয়ে যাওয়া রেখার সমীকরণ পেতে দুটি বিন্দু (x₁, y₁) ও (x₂, y₂) লিখুন।

সূত্র

m = \frac{y_2 - y_1}{x_2 - x_1}

Slope is rise over run between the two points.

y = mx + b,\quad b = y_1 - m x_1

The y-intercept b is where the line crosses the y-axis.

m = (7 − 3)/(3 − 1) = 2.

b = 3 − 2·1 = 1, so y = 2x + 1.

The two points have the same x value, so the line is vertical: its equation is x = constant.

Yes — “gradient” is the common term in the UK and Australia.
