A coordinate plane shows the x and y axes ranging from negative 8 to 8 in increments of 1. An upward line with arrows at both ends passes through the first, fourth, and third quadrants. The line passes through left parenthesis 2 comma 3 right parenthesis, and left parenthesis negative 2 comma negative 5 right parenthesis.

To identify the correct sketch of the graph based on the features given for the function, let's break down the information:

  1. Initial Value of 2: This indicates that when \( x = 0 \), \( y = 2 \). Therefore, the y-intercept is at (0, 2).

  2. Slope of -1: A slope of -1 means that for every unit increase in \( x \), \( y \) decreases by 1. This produces a line that is decreasing from left to right.

With these two pieces of information, we can outline the characteristics of the function:

  • The line should intersect the y-axis at (0, 2).
  • Since the slope is -1, the line will move downward at a 45-degree angle as it moves from left to right.

Now, let's evaluate the given responses:

  1. Response 1: This describes an upward line that is not consistent with a negative slope.

  2. Response 2: This describes a downward line that intersects the y-axis at (0, 2) and has a negative slope. This is a valid representation of the function.

  3. Response 3: This describes an upward line, which does not match with the negative slope.

  4. Response 4: This describes another upward line, which again does not fit the requirements.

Based on the analysis, Response 2 is the correct sketch of the graph, as it exhibits the qualitative features of the function with a downward line intersecting the y-axis at (0, 2) and a slope of -1.
