During an experiment that Paul and Dawn performed the stretch of a spring was directly proportional to the force applied to the spring. When they put the data on a graph, they would expect to have what type of curve?

Answers: Hyperbola, parabola, straight line, none of the above answers.

Proportionality of one variable with another, as in this case, indicates a linear relationship.

If the stretch of a spring is directly proportional to the force applied, the relationship can be represented by a straight line. Hence, when Paul and Dawn plot the data on a graph, they would expect to have a straight line curve.

To determine the shape of the curve on the graph, we need to understand the relationship between the stretch of the spring and the force applied. In this case, it is stated that the stretch of the spring is directly proportional to the force.

When two variables are directly proportional, their relationship can be represented by a straight line on a graph. Therefore, the expected curve on the graph would be a straight line.

To get a straight line on the graph, you would need to plot the force applied to the spring on the x-axis and the stretch of the spring on the y-axis. Then, each data point would represent a specific force and its corresponding stretch, and connecting these points would form a straight line.
