About this calculator
The UTIQO Slope Calculator computes the slope of a line from two points, or from a linear equation, and provides the equation of the line in slope-intercept form. It is designed for students, teachers, and professionals who need quick and accurate slope calculations for algebra, geometry, and real-world applications.
How to use

Enter the coordinates of the first point in the x₁ and y₁ fields.
- 2
Enter the coordinates of the second point in the x₂ and y₂ fields.
- 3
Click Calculate to see the slope, y-intercept, line equation, and angle of inclination.
Frequently asked questions
What does an undefined slope mean?
An undefined slope occurs when the line is vertical, meaning x₁ = x₂. The change in x is zero, so division by zero is undefined.
Can I enter fractions as coordinates?
Yes, you can enter fractions as decimal numbers or as fractions in the form 'a/b'.
How do I find the slope from a linear equation?
Rearrange the equation into slope-intercept form (y = mx + b). The coefficient of x is the slope.
