Yolanda's Graph
Yolanda made a graph of her data. “I see a pattern,” she said. “It looks like the data points are on a straight line.” Yolanda tried to draw a straight line through her data points. She could not get a line to go through all the points. She tried to fit the points as best she could. Scientists and mathematicians call that a best-fit line.
