To interpret a graph, look for key features, like the x and y intercepts, as well as the slope. The x and y intercepts happen when one of the quantities is zero, which is important A point where lines intersect tells us that some relationships are taking on the same input and output values at that key point. The slope tells you whether something is increasing or decreasing and how fast it is changing, and the units on the slope (y units on top of x units) can help tell a rate of change. If the slope changes, consider whether it is getting more or less steep and whether something is changing from increasing to decreasing.
