The table shows the height of a plant as it grows. what equation in point-slope form gives the plant’s height at any time? let y stand for the height of the plant in cm and let x stand for the time in months.

time(months) plant height
3 15
5 25
7 35
9 45

a. y – 15 = (x – 3)
b. y – 15 = 5(x – 3)
c. y – 3 = (x – 15)
d. the relationship cannot be modeled.

Me because some of question i don’t understand

Asays "we are both knaves" and b says nothing. exercises 24–31 relate to inhabitants of an island on which there are three kinds of people: knights who always tell the truth, knaves who always lie, and spies (called normals by smullyan [sm78]) who can either lie or tell the truth. you encounter three people, a, b, and c. you know one of these people is a knight, one is a knave, and one is a spy. each of the three people knows the type of person each of other two is. for each of these situations, if possible, determine whether there is a unique solution and determine who the knave, knight, and spy are. when there is no unique solution, list all possible solutions or state that there are no solutions. 24. a says "c is the knave," b says, "a is the knight," and c says "i am the spy."
