er minute. Assume the plane continues at the same rate of descant. The plane's helght and minutes above the ground are related to each other Identify the variables in this situation: xa minutes ya height What is the glven Information in this problem (find all that apply)? y-intercept 30.000 slope2000, one point a second point ) 3. Write an equation to model the situation. y2000x130.000 b. Use your equation to find the altitude of the plane after S minutes, Suppose you receive $100 for a graduation present, and you deposit it in a savings account. Then each week thereafter, you add $5 ta the account but no interest is earned. The amount in the account is a function of the number of weeks that have passed. you Identify the variables in this situation: x- What is the given information in this problem (And all that apply)? pintercept slope _- one point ) a second point ) a Find an equation for the amounty you have afterx weeks,
