Math Problem Statement

y - x ≥ 2

Solution

The inequality provided is:

yx2y - x \geq 2

Solution and Interpretation:

  1. Rewriting the inequality: yx+2y \geq x + 2

  2. Graphical Representation:

    • This represents a half-plane in a two-dimensional coordinate system.
    • The boundary line is y=x+2y = x + 2, which is a straight line with a slope of 11 and a yy-intercept of 22.
    • The inequality yx+2y \geq x + 2 means that the solution set includes all points on or above the line y=x+2y = x + 2.
  3. Graphing Steps:

    • Plot the line y=x+2y = x + 2. It passes through the points:
      • (0,2)(0, 2) (when x=0x = 0),
      • (2,0)(-2, 0) (when y=0y = 0).
    • Since it is \geq, shade the region above the line.

Follow-Up Questions:

  1. What is the slope and intercept of the line y=x+2y = x + 2, and how do they determine the line's properties?
  2. How does the solution region of yx+2y \geq x + 2 differ from y>x+2y > x + 2?
  3. Can you identify two points that satisfy yx+2y \geq x + 2?
  4. How would this inequality change if yx2y - x \leq 2?
  5. How would you graph y=x+2y = x + 2 without using a calculator?

Tip:

Always start by plotting the equality boundary for inequalities and determine the correct region to shade by testing a point!
