#### Answer

Point A:
$y=\frac{1}{2}x$
$y=\frac{1}{2}\times(0)$
$y=0$
Point B:
$y=\frac{1}{2}x$
$y=\frac{1}{2}\times(-4)$
$y=-2$
Point C:
$y=\frac{1}{2}x$
$y=\frac{1}{2}\times(2)$
$y=1$

#### Work Step by Step

To get the coordinates of point A, substitute the given x-value of 0 into the given equation $y=\frac{1}{2}x$ to get the y-value of y=0. Hence, we know that when x is 0, y is 0. i.e (0,0) is a point on the line.
To get the coordinates of point B, substitute the given x-value of -4 into the given equation $y=\frac{1}{2}x$ to get the y-value of y=-2. Hence, we know that when x is -4, y is -2. i.e (-4,-2) is a point on the line.
To get the coordinates of point C, substitute the given x-value of 2 into the given equation $y=\frac{1}{2}x$ to get the y-value of y=1. Hence, we know that when x is 2, y is 1. i.e (2,1) is a point on the line.
Graph points A, B and C using their respective x and y values. Using a ruler, draw a straight line passing through all three points to graph the equation of $y=\frac{1}{2}x$.
