Identify the error in graphing y<2x1y < 2x - 1: Step 1: Plot y-intercept at -1. Step 2: Use slope 2 to find next point (1, 1). Step 3: Draw a solid line through points. Step 4: Shade below the line.

A

Step 3

B

Step 1

C

Step 2

D

Step 4

Correct Answer: A

Choice A is the correct answer. Check line type.

  1. Inequality: y<2x1y < 2x - 1
  2. Symbol: << is strict.
  3. Line Type: Must be DASHED.
  4. Error: Step 3 drew a SOLID line.

?�� Strategic Tip: Always check solid vs dashed first.

Choice B is incorrect because intercept is correct. Choice C is incorrect because slope is correct. Choice D is incorrect because shading below (<<) is correct.
