Abby is completing a science experiment in Mrs. Gormley's class.
She finds that when she boils 4 ounces of a solution, it becomes a solid that has a mass of 2 grams. When she boils 8 ounces of a solution, it becomes a solid that has a mass of 3 grams.
She records the data as the points (4, 2) and (8,3).
Plot the given points ((4,2) & (8,3)) in the question and connect them to create a line all across the graph.
