To answer this question, we first need to identify the slope and y-intercept of the line given by the equation \(y = x - 2\).
- Identify the slope and y-intercept:
From the equation \(y = x - 2\), we can see that:
- The slope (m) is 1 (the coefficient of x).
- The y-intercept (b) is -2 (the constant term).
Now that we have identified the slope to be 1 (m=1) and the y-intercept to be -2 (b=-2), we will look for a graph of a line with these characteristics:
-
Characteristics of the desired line: The line will have the following characteristics:
- It will pass through the point (0, -2) because that is the y-intercept.
- It will have a slope of 1, meaning for every unit increase in x, y increases by 1.
-
Analyzing each option:
-
Option 1: A coordinate plane with a line starting at (−2, −4), passing through (0, −2) and (2, 1).
- This line passes through (0, -2), which is correct for the y-intercept. The slope can be calculated by checking the rise/run between points, and it is indeed 1. This option works.
-
Option 2: A coordinate plane with a line passing through (−3, 0) and (0, 2).
- The y-intercept is at (0, 2), which does not match the required y-intercept of -2. This option does not work.
-
Option 3: A coordinate plane with a line passing through (0, 2) and (2, -1).
- The y-intercept is at (0, 2), which again does not match our requirement of -2. This option does not work.
-
Option 4: A coordinate plane with a line passing through (−3, 0) and (0, −2).
- This line passes through (0, -2), matching the required y-intercept. The slope can also be computed, and it is not 1.
Only the first option has both the correct y-intercept and slope characteristics.
Thus, the correct graph is the first option: A coordinate plane with a line starting at (−2, −4), passing through (0, −2) and (2, 1).
