graph the line $y = -1$.
graph the line $y = -1$.
Answer
Explanation:
Step1: Analyze the equation
The equation (y = - 1) means for any value of (x), (y) is always (-1).
Step2: Find points
We can choose some (x) - values. For example, when (x = - 4), (y=-1); when (x = 0), (y = - 1); when (x=4), (y=-1). So the points are ((-4,-1)), ((0,-1)), ((4,-1))
Step3: Plot the points and draw the line
Plot the points ((-4,-1)), ((0,-1)), ((4,-1)) on the coordinate plane. Then draw a straight line passing through these points.
Answer:
The graph of the line (y = - 1) is a horizontal line passing through all points ((x,-1)) for any real number (x).
