(40,25.20)(72,21.36)
slope = (21.36 - 25.20) / (72 - 40) = -3.84 / 32 = -0.12
y = mx + b
slope(m) = -0.12
(40,25.20)...x = 40 and y = 25.20
sub and solve for b, the y int
25.20 = -0.12(40) + b
25.20 = - 4.8 + b
25.20 + 4.8 = b
30 = b
ur equation is : y = -0.12x + 30....where x is ur minutes, and y is remaining credit.
after 86 minutes...
y = -0.12(86) + 30
y = - 10.32 + 30
y = 19.68 <===

Answer:

Step-by-step explanation:
on the left side u add 4k+3k=7k
on the right side u subtract 2k-6k=4k
then on the left side u add 2 to each side and u get rid of the 2 on the left side
on the right side u add 5+2=7
then on the right side u add 4k on each side and get rid of the 4k on the right
on the left u subtract 7k-4k=3k
on both sides divide by 3
