Writing Suppose the relationship between x and y is proportional. When x is 29, y is 275.5. Find the constant of proportionality of y to x. Use the constant of proportionality to find x when y is 408.5. Use pencil and paper. Explain how you can tell a relationship that is proportional from a relationship that is not proportional.

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
