To find the solutions of the equation, we can substitute x=4 into the given equation and solve for y.
y = -1/2 * x
y = -1/2 * 4
y = -2
So one solution of the equation is (4,-2)
To find other solutions, we can choose different values of x and solve for y.
If x=-2:
y = -1/2 * -2
y = 1
So another solution of the equation is (-2,1)
If x=2:
y = -1/2 * 2
y = -1
So another solution of the equation is (2,-1)
If x=0:
y = -1/2 * 0
y = 0
So another solution of the equation is (0,0)
Therefore, the solutions of the equation y = -1/2 * x are: (4,-2), (-2,1), (2,-1), and (0,0)
{x=4
{-y=1/2x
(4,2)
(-2,4)
(2,-4)
(4,-2)
