Answer
y = 2x - 6
- Y-intercept: (0, -6).
- X-intercept: (3, 0).
- Slope 2: rise 2 for every 1 unit right.
How to use the linear graph calculator
Enter the slope m and y-intercept b to plot y = mx + b. The graph marks the x- and y-intercepts and draws the slope triangle so slope-intercept form connects to the line's shape.
- Enter the slope m and the y-intercept b.
- Read the y-intercept, x-intercept, and slope triangle on the graph.
- Use related calculators to find slope or intercepts numerically.
Formula or method
A linear function has the form y = mx + b.
Worked examples
Graph y = 2x - 6
Problem: m = 2, b = -6
Solution: The line crosses the y-axis at -6, crosses the x-axis at 3, and rises 2 units for every 1 unit right.
