y=-2+x

Here’s what the equation y = -2 + x means and some quick facts you can use for exams:

• Rewrite in standard form: y = x - 2 is the same as x - y = 2.
• Slope-intercept form: slope m = 1, y-intercept b = -2.
• Intercepts:
  • y-intercept: (0, -2)
  • x-intercept: set y = 0 → x = 2, so (2, 0)
• Two convenient points on the line: (0, -2), (1, -1), (2, 0)
• Graph: a diagonal line with a 45-degree angle crossing y-axis at -2 and rising one unit for every step right.

If you want, I can give a couple of practice problems (e.g., find a perpendicular line through a point, or solve intersections with another line).
