A function slope and intercepts calculator (or function slope and intercepts calculator) calculates slope, x-intercept, and y-intercept from linear functions. This calculator finds all intercepts and slope from any linear equation in slope-intercept form (y = mx + b), standard form (Ax + By + C = 0), or from two points. Perfect for analyzing linear functions and finding intercepts.
A slope intercept calculator from equation (or slope intercept calculator from equation) extracts slope and intercepts directly from linear equations. For slope-intercept form (y = mx + b), slope = m and y-intercept = b. A gradient and y intercept calculator (or gradient and y intercept calculator) finds gradient (slope) and y-intercept from equations. Gradient is another term for slope. This calculator works with any linear equation format.
A y-intercept from 2 points calculator (or y-intercept from 2 points calculator) calculates y-intercept from two given points: 1) Calculate slope m = (y₂ - y₁)/(x₂ - x₁). 2) Use one point to find y-intercept: b = y - mx. 3) Y-intercept = (0, b). A circle intercepts calculator (or circle intercepts calculator) finds where a circle intersects the x-axis and y-axis. For circle equation (x-h)² + (y-k)² = r², set x=0 to find y-intercepts and y=0 to find x-intercepts.

Common questions about intercepts and linear equations
An x-intercept is the point where a line crosses the x-axis. At this point, y = 0. It's found by setting y = 0 in the equation and solving for x.
A y-intercept is the point where a line crosses the y-axis. At this point, x = 0. It's found by setting x = 0 in the equation and solving for y.
For y-intercept: substitute x = 0 and solve for y. For x-intercept: substitute y = 0 and solve for x. For slope-intercept form y = mx + b, the y-intercept is b and x-intercept is -b/m.
Use the slope formula: m = (y₂ - y₁)/(x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the two points on the line.
Slope-intercept form is y = mx + b (m = slope, b = y-intercept). Standard form is Ax + By + C = 0. Both can be used to find intercepts, but slope-intercept form makes it easier to identify the slope and y-intercept directly.
Yes. Horizontal lines (y = constant) have no x-intercept unless y = 0. Vertical lines (x = constant) have no y-intercept unless x = 0. Lines passing through the origin have both intercepts at (0, 0).
To convert slope-intercept (y = mx + b) to standard form: move all terms to one side. To convert standard form to slope-intercept: solve for y. To find slope-intercept from two points: calculate slope, then use one point to find y-intercept.
Intercepts are used in economics (break-even points), physics (initial conditions), engineering (system analysis), and many other fields where linear relationships model real-world phenomena.
Plot the x-intercept on the x-axis and the y-intercept on the y-axis. Draw a straight line connecting these two points. This line represents the linear equation.
Most lines don't pass through the origin. The x-intercept and y-intercept will be different points. Only lines of the form y = mx (with no constant term) pass through the origin.
