What is the slope of the line y = x - 2?

-1
2
0
1

The correct answer is: 1

The slope of a line is the change in y values over the change in x values. In the given equation, y = x - 2, the coefficient of x is 1, which means that for every increase of 1 in the x value, the y value will increase by 1. Therefore, the slope of the line is 1. Option A, -1, is incorrect because it does not match the coefficient of x in the equation. Option B, 2, is incorrect because it does not take into account the coefficient of x and only represents the y-intercept of the line. Option C, 0, is incorrect because it is the slope of a horizontal line, but the given equation does not represent a horizontal line.
