Slope-Intercept Form Calculator
Build the equation y = mx + b from a slope and a point, or from two points, with clear steps.
Build y = mx + b
Answer
y = 2x + 1
- Use y = mx + b.
How to use the slope-intercept calculator
Slope-intercept form is one of the most common ways to write a line. This calculator finds b and writes the final equation.
- Enter a slope and one point on the line.
- Substitute the point into y = mx + b.
- Solve for b.
- Write the final equation.
Formula or method
y = mx + b.
Worked examples
Find y = mx + b
Problem: m = 2 through (3, 7)
Solution: 7 = 2(3) + b, so b = 1 and y = 2x + 1.
