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

Point A: $y=-3x$ $y=-3(0)$ $y=0$ Point B: $y=-3x$ $y=-3(-2)$ $y=6$ Point C: $y=-3x$ $9=-3(x)$ $x=\frac{9}{-3}$ $x=-3$
To find the coordinates of point A and B, substitute the given y-value into the equation $y=-3x$ to find the x-value for that corresponding y-value. To find the coordinates of point C, substitute the given x-value into the equation $y=-3x$ to find the y-value for that corresponding x-value. Plot points A, B and C on the graph given and draw a straight line that passes through all three points.
