Y - 1 = m(x - 1) . . . (1)
y = mx - m + 1 . . . (2)
From(2), -m + 1 = 2 => m = 1 - 2 = -1
Substituting for m in (1), we have:
y - 1 = -(x - 1) . . . (3)
Equation of a line in general form is given by ax + by = c
From (3), y - 1 = -x + 1
x + y = 1 + 1
Therefore, required equation is x + y = 2.
Answer:
The sequence above is a geometric sequence
For an nth in a geometric sequence

where n is the number of terms
a is the first term
r is the common ratio
From the question
a = 45
r = 15 / 45
The explicit formula for the sequence is
U(n) = 45(1/3)^n-1
Hope this helps you
