Дай ответ

Determine which graph represents the function y = 0.5x - 2.

Solution

The question asks to identify the graph of the function y=0.5x2y = 0.5x - 2.

Let's analyze the function:

  1. Slope (m): The slope of this line is 0.50.5, which means the line rises by 0.5 units for each unit it moves to the right.
  2. Y-intercept (b): The y-intercept is 2-2, meaning the line crosses the y-axis at (0,2)(0, -2).

Looking at the answer choices:

  • The correct graph will have a line with a gentle positive slope (since 0.50.5 is a positive but small slope).
  • The line must cross the y-axis at 2-2.

From the image, Option B matches this description: it has a positive slope and crosses the y-axis at 2-2.

Answer:

The correct option is B.
