y = 2x -10
Step-by-step explanation:
slope is change of y over the change in x
10 - (-14) = 24
10 - 2 = 8
24/8 = 3
y -10 = 2 (x-10)
y - 10 = 2x -20
y = 2x -10

Answer:
RM 687.3
Step-by-step explanation:
Number of members = 257
Each member makes = RM 25
So, total money = 257×25= RM 6425
1- 45 % of 6425 = 45 /100 × 6425=RM 2891.25
So, RM 2891.25 Â was spent for the year-end banquet. Hence remaining money after this expenditure = 6425-2891.25= RM 3533.75
2- 65 % of this remaining money = 65 /100 × 3533.75= RM 2296.45
So, RM 2296.5 were spent on souvenirs. Hence remaining amount = 3533.75 - 2296.45 = Â RM 1237.3
3- Out of this remaining money RM 550 were spent for club jersey booking fees.
So, amount left = 1237.3 - 550 = RM 687.3
