Question
For the equation, find the slope m and y-intercept (0, b) (when they exist). (If an answer does not exist, enter DNE.)y = −2
Solution
The equation given is y = -2. This is a horizontal line parallel to the x-axis.
-
The slope (m) of a horizontal line is always 0. This is because there is no change in the y-values as we move along the line, hence the rise over run (which gives the slope) is 0.
-
The y-intercept (b) is the y-coordinate where the line crosses the y-axis. For the given equation, the line crosses the y-axis at y = -2. So, the y-intercept is -2.
So, the slope m = 0 and the y-intercept b = -2.
