Answer: Use a compass to measure the length of AB. Draw an arc from point B (or point A) with that distance. Extend line AB through that arc and label the intersection as point C. AC is twice the length of AB.
To find the point on the graph of g, we use the horizontal shift for the x-coordinate 4 to get 4–2=2, and the vertical shift for the y-coordinate –3 to get –3–5=–8.
