Question 1

What is a Line Equation Calculator?

Accepted Answer

The equation of a line in slope-intercept form is y = mx + c, where m is the slope (gradient) and c is the y-intercept. It describes every straight line in 2D space.

Question 2

How does the Line Equation Calculator work?

Accepted Answer

Slope m = (y₂−y₁)/(x₂−x₁) Then: y-intercept c = y − mx Then: Parallel lines have equal slopes Then: Perpendicular lines: m₁×m₂ = −1.

Question 3

Can you give an example of how to use the Line Equation Calculator?

Accepted Answer

Example: Input Points (0,2) and (3,8) gives a result of m = (8−2)/(3−0) = 2, c = 2, so y = 2x + 2.

Question 4

Is the Line Equation Calculator free to use?
