This is a linear function in slope-intercept form y = 2x − 1.
Quick facts:
- Slope (m) = 2
- y-intercept = (0, −1)
- x-intercept (set y = 0) → x = 1/2, so (1/2, 0)
- Domain = (−∞, ∞); Range = (−∞, ∞)
- Solved for x: x = (y + 1)/2
Example points: x = −1 → y = −3; x = 0 → y = −1; x = 1 → y = 1; x = 2 → y = 3.
Would you like a graph, intersection with another line, or to solve for a particular y or x?
