Use the image to answer the question.

A coordinate plane shows the x-axis ranging from negative 9 to 9 in increments of 1 and the y-axis ranging from 11 to negative 11 in increments of 1. A line with arrows at both ends joins two plotted points.
The coordinates of the plotted points are as follows: left parenthesis 0 comma 3 right parenthesis, and left parenthesis 3 comma 2 right parenthesis.

To determine if the given graph correctly represents the equation \( y = -13x + 4 \), we need to analyze the characteristics of the line.

  1. Slope Calculation: The slope \( m \) of the equation \( y = -13x + 4 \) is \(-13\), which is a negative slope. This means that as \( x \) increases, \( y \) should decrease.

  2. Y-intercept Calculation: The y-intercept occurs when \( x = 0 \). Substituting \( x = 0 \) into the equation gives: \[ y = -13(0) + 4 = 4. \] Therefore, the y-intercept is \( (0, 4) \).

  3. Plotted Points: The graph indicates two plotted points: \( (0, 3) \) and \( (3, 2) \). The first point, \( (0, 3) \), shows the y-intercept is at 3, not 4, which conflicts with the calculated y-intercept of the equation.

  4. Slope Between Points: The slope between the two points \( (0, 3) \) and \( (3, 2) \) can be calculated as: \[ m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 3}{3 - 0} = \frac{-1}{3}, \] which is positive, indicating the line would rise rather than fall, further confirming that this does not match the expected negative slope of \(-13\).

Based on this analysis, the correct response is:

No, it is not the correct graph because this graph used \( (0, 3) \) as the y-intercept.
