Graph the equation by plotting points
Y = 1/2 x - 1
To graph the equation y = 1/2x - 1, we can choose values of x, substitute them into the equation to find the corresponding values of y, and then plot the points on a graph.
Let's choose the following values of x: -2, 0, and 2.
When x = -2:
y = 1/2(-2) - 1
y = -1 - 1
y = -2
So, the first point is (-2, -2).
When x = 0:
y = 1/2(0) - 1
y = -1
So, the second point is (0, -1).
When x = 2:
y = 1/2(2) - 1
y = 1 - 1
y = 0
So, the third point is (2, 0).
Now, we can plot the three points on a graph:
x | y
-2 | -2
0 | -1
2 | 0
The graph will have the shape of a straight line that passes through these three points.
