Solve It! The red line shows the altitude of a hot-air balloon during its linear descent. What is an equation of the line in slope-intercept form? Hint: What is the altitude of the balloon when it starts its descent at x = 0?

Recall: The general equation used to represent slope-intercept form is:
This format is named slope-intercept form because the equation reveals the slope, m, and y-intercept, b.

Take Note: What is the general equation used to represent point-slope form ?
Enter the equation as it is shown in the Key Concept box above.

Take Note: Explain why point-slope form is given that name.

Problem 1 Got It?

Problem 2 Got It? What is the graph of the equation?
Be sure to include relevant graph detail: label axes, indicate units on both axes, and use arrows to represent end behavior, as appropriate.

Problem 3 Got It? Reasoning: Rewrite the equations in Problem 3 and in the previous item in slope-intercept form. Compare the two rewritten equations. What can you conclude?

Problem 4 Got It? The table shows the number of gallons of water y in a tank after x hours. The relationship is linear. What is an equation in point-slope form that models the data?
