Susan wants to learn more about how temperature changes in her city. She creates a table that shows the low temperatures for two days. The table is below. Which of the following statements is correct? Day Temperature 1 -8° 2 -3°       The slope between the data points is positive because two negatives makes a positive.     The slope between the two data points is negative because the temperature decreased from Day 1 to Day 2.     The slope between the two data points is positive because the temperature increased from Day 1 to Day 2.     The slope between the two data points is negative because the two temperatures are negative.

A clothing business finds there is a linear relationship between the number of shirts,n, it can sell and the price,p, it can charge per shirt. In particular, historical data shows that 6000 shirts can be sold at a price of $56, while 9000 shirts can be sold at a price of $35. Give a linear equation in the form p = mn + b that gives the price p they can charge for ʼn shirts. Answer: p= Round the value of your slope to three decimal places. Be careful to use the proper variable and use the Preview button to check your syntax before you submit your answer.

At Hanna's hair salon, a full-time starting stylist gets paid a base amount of pay per week, then $10 per haircut. Vanessa recently started working at the salon. In the first week, Vanessa saw 16 clients and took home $635 (not including any tips). Vanessa wants to represent pay by writing a linear equation and is deciding between writing it in slope-intercept form or using the point-slope formula. a) If Vanessa just wants to use the equation to most efficiently figure out how many clients will need to see to make a $1,000 in a week, which one should choose? Explain. b) If Vanessa wants to use the equation to understand how payment works, which one should choose? Explain.
