Why this page exists

Line equations are easier to check when a point and slope are turned directly into equation form instead of being rewritten by hand every time. This calculator helps visitors write a line in point-slope form from a point and a slope and also shows the slope-intercept form for comparison.

Calculator

Point-slope form calculator

Write the equation of a line in point-slope form from a point and a slope, with a slope-intercept view for comparison.

Result

y - 5 = 3/2(x - 2)

Estimated line equation written in point-slope form from the point and slope entered, with a slope-intercept view for comparison.

Point-slope formy - 5 = 3/2(x - 2)

Slope-intercept formy = 3/2x + 2

Slope used3/2

Point used(2, 5)

The point (2, 5) with a slope of 3/2 gives the point-slope equation y - 5 = 3/2(x - 2).
Rewriting the same line in slope-intercept form gives y = 3/2x + 2.
Use the result for algebra checks, graphing practice, or to move quickly between line-equation forms without rewriting the relationship by hand.

This is standard line-equation math. The calculator assumes the point and slope entered describe a valid line and rewrites the result into readable forms.

How it works

What the calculator is doing

Enter the x-coordinate, y-coordinate, and slope.

The calculator applies the point-slope equation using the point and slope entered.

It displays the line in point-slope form and rewrites the same relationship in slope-intercept form.

Understanding your result

This is standard line-equation math. Fractional slopes are accepted, and a slope of zero is handled as a horizontal line.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Check an algebra answer quickly

The calculator can help confirm whether a point and slope were turned into the correct line equation.

Move between line-equation forms

Seeing both point-slope and slope-intercept form can make graphing and homework checks easier.

Use it with other coordinate tools

Point-slope problems often sit alongside slope, midpoint, and distance questions on the same set of points.

FAQ

Common questions

How is the point-slope equation written here?

The calculator uses the point and slope entered in the standard point-slope setup and shows the resulting equation directly.

Can I enter a fractional slope?

Yes. Fractions like 3/2 are accepted as long as the denominator is not zero.

Why show slope-intercept form too?

It makes the same line easier to compare with graphing instructions, textbook examples, or other algebra problems that use y = mx + b form.
