## Algebra: A Combined Approach (4th Edition)

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: $y=\frac{1}{2}x$ $y=\frac{1}{2}\times(2)$ $y=1$
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 $y=\frac{1}{2}x$.
