はじめに
Point-Slope Calculator — Find a line equation from a point and a slope. Enter X1, Y1, Slope to get an instant, accurate result.
計算式
Given a point (x₁,y₁) and slope m, the line equation y − y₁ = m(x − x₁) is rearranged to slope-intercept form y = mx + b, where b = y₁ − m×x₁.
ステップごとの説明
- Enter the X1.
- Enter the Y1.
- Enter the Slope.
- Click Calculate to see your result instantly.
実例
Example: With X1 = 1, Y1 = 2, Slope = 3, the Point-Slope Calculator gives Slope: 3, Intercept: -1, Equation: y = 3x + -1.
よくある質問
What does the intercept represent?
The y-value where the line crosses the y-axis (where x = 0).
Do I need two points?
No, this calculator only needs one point and the slope.
What inputs does the Point-Slope Calculator need?
You'll need to provide: X1, Y1, Slope. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Point-Slope Calculator?
The Point-Slope Calculator applies the formula exactly as calculated — Given a point (x₁,y₁) and slope m, the line equation y − y₁ = m(x − x₁) is rearranged to slope-intercept form y = mx + b, where b = y₁ − m×x₁. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Point-Slope Calculator free to use?
Yes, the Point-Slope Calculator is completely free, requires no signup, and runs instantly in your browser.
点と傾きの計算機について
The Point-Slope Calculator uses a real, verifiable formula — Given a point (x₁,y₁) and slope m, the line equation y − y₁ = m(x − x₁) is rearranged to slope-intercept form y = mx + b, where b = y₁ − m×x₁. — so results are accurate every time, not an approximation.
