how do you graph y=-2?
Draw a straight horizonal line that passes through y = -2 on the (vertical) y axis. It should extend over the full width of the graph.
Yes, y=-2 is the equation of the line that contains all the points which have their y-coordinates as -2, such as (3,-2), (5,-2), (-4,-2), etc. Plot those. You'll see that they all lie on a horizontal line which is 2 units below the x-axis. That line is the graph.
Because it not greater or lesser than so the line will only be drawn on figure -2, on y-axis
Because it not greater or lesser than so the line will only be drawn on figure -2, on y-axis on the left side where we have the nagative numbers.
To graph the equation y = -2, you can follow these steps:
1. Start by drawing a coordinate plane, which consists of two perpendicular lines called the x-axis (horizontal) and the y-axis (vertical).
2. Since the equation does not contain any variables or terms involving x, it means that the value of x can be any real number. This implies that the graph is a horizontal line parallel to the x-axis.
3. Now, locate the y-intercept of the equation, which is -2. The y-intercept represents the point (0, -2) on the y-axis.
4. Mark this point on the graph by placing a dot at (0, -2).
5. Since the line is horizontal, it will extend infinitely to the left and right of the y-intercept.
6. Draw a straight line passing through the y-intercept (-2) that extends infinitely in both directions.
After completing these steps, you should have a graph of the equation y = -2, which is a horizontal line passing through the point (0, -2).
