Kikokotoo cha Mteremko

Weka nukta mbili (x₁, y₁) na (x₂, y₂) ili kupata mteremko na mlinganyo wa mstari unaopita katika nukta hizo.

Tokeo

Weka thamani kisha bonyeza Kokotoa ili kuona tokeo.

Fomula

m=y2−y1x2−x1m = \frac{y_2 - y_1}{x_2 - x_1}

Slope is rise over run between the two points.

y=mx+b,b=y1−mx1y = mx + b,\quad b = y_1 - m x_1

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

Jinsi ya kutumia kikokotoo hiki

  1. Enter the coordinates of two different points.
  2. Press Calculate to see the slope, intercept and equation.

Mfano uliotatuliwa

Line through (1, 3) and (3, 7)

m = (7 − 3)/(3 − 1) = 2.

b = 3 − 2·1 = 1, so y = 2x + 1.

Maswali yanayoulizwa mara kwa mara

What does an undefined slope mean?

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

Is slope the same as gradient?

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