Answer:
y = 2x-5
Step-by-step explanation:
y = 2x + 4 passes through (4,3)
y - 3 = 2(x - 4) + 0
y = 2x-8 + 3
4n (3n - m)
See what they both have, pull it to the outside, put what is left inside.
4mm
(-1)* (3)^(n-1)
common ratio is 3 and the first term is -1
the explicit formula is a * r^ ( n-1)
i.e., (-1) * 3^(n-1)
