Problem Solving Strategy – Draw a Graph
We can use the technique of drawing a linear graph from known information to extrapolate (extend) or interpolate (look at values inside) information. We usually need at least 2 data points (x, y) to make a straight line for the graph.
We MUST use graph paper when we are drawing these graphs. The more accurate you are with building the graph, the better and more accurate your results can be.
