Note that the prey population size is on the left vertical axis and the predator population is on the right vertical axis and that the scales of the two are different after Huffaker 1958 fig18. It is apparent from the graph that both populations showed cyclical behavior and that the. Below are shown the graph of 6 functions.

From there run 6 units in a positive direction to 3 425. Find the y-intercept of a linear function using the slope and a given point First identify the slope and a point on the graph. State the slope and the y-intercept of each line below.

The results of one of the many permutations of his experiments are graphed below. If the slopes are the same then the points are collinear. Employing the Guidelines in Table 4 for Graphed Scores and Weekly Progress Monitoring Roberts three consecutive scores below the goal signals inadequate progress and a prompt for his teacher to adjust instruction.

Roberts slope at weeks 8 and 9 72 and 57. Practice finding the slopes of the lines shown on the graphs. Use the slope formula.

If the data points appear to form a straight line an equation of that line can be used to predict the value of one variable based on the value of the other variable. You may also want to check out this short introduction to. One reason for using this type of graph is to look for relationships between the variables.
