Find the graph of the equation by plotting points
y= - 2x
To find the graph of the equation y = -2x, we can choose several x-values, plug them into the equation, and calculate the corresponding y-values.
Let's choose four x-values: -2, -1, 0, and 1.
When x = -2, y = -2(-2) = 4.
When x = -1, y = -2(-1) = 2.
When x = 0, y = -2(0) = 0.
When x = 1, y = -2(1) = -2.
Plotting these points on a graph will give us:
(-2, 4)
(-1, 2)
(0, 0)
(1, -2)
Connecting these points will give us a line. The graph of y = -2x is a straight line that passes through these points.
