Question

PLEASE HELP IVE BEEN WORKING SO LONG ON THIS

Answer 1

Part A The 4th bubble y= -55x+1630

Part B 1630

Part C 55

Explanation:

Part A Use slope to find answer. In this example, points (1,599) and (4,1430).

Next use equation y1-y2/x1-x2. In this example, 1599-1430/1-4 which equals 169/-3 and that equals -56.3333333333333333333333. Since y= -55x+1630 is closer, choose that answer.

Part B use y intercept. The y intercept is 1630

Part C Use the slope -55. It decreases by 55.
