An illustration shows a coordinate plane with four quadrants. The x-axis and y-axis both range from negative 4 to 4 in one unit increments. An upward slanting line is graphed on the coordinate plane. The line passes through points plotted at left parenthesis negative 2 comma 0 right parenthesis, and left parenthesis 0 comma 2 right parenthesis.

An illustration shows a coordinate plane with four quadrants. The x-axis and y-axis both range from negative 4 to 4 in one unit increments. A circle is graphed on the coordinate plane. The circle is formed by connecting points plotted at left parenthesis negative 2 comma 0 right parenthesis, left parenthesis 0 comma 2 right parenthesis, and left parenthesis 2 comma 0 right parenthesis.

An illustration shows a coordinate plane with four quadrants. The x-axis and y-axis both range from negative 5 to 5 in one unit increments. A parabola opening upward is graphed on the coordinate plane. The parabola is formed by connecting points plotted at left parenthesis negative 4 comma 2 right parenthesis, left parenthesis negative 2 comma 0 right parenthesis, and left parenthesis 0 comma 2 right parenthesis.

The function \( y = x + 2 \) represents a linear equation where the slope is 1 and the y-intercept is 2. This means that the line crosses the y-axis at the point (0, 2) and rises diagonally with a slope of 1 (for every increase of 1 in \( x \), \( y \) increases by 1).

To identify the correct graph among the options provided, look for a straight line that passes through the point (0, 2) and goes upwards on the coordinate plane. Additionally, it should also pass through another point that can be calculated from the equation, such as (−2, 0) since plugging in -2 gives:

\[ y = -2 + 2 = 0 \]

Based on the description of the options:

  1. The graph that describes a straight line passing through (−2, 0) and (0, 2) is the correct graph of the function \( y = x + 2 \).

Therefore, the correct response is the graph of the upward slanting line that passes through the points (−2, 0) and (0, 2).
