Answer:
y = 5x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (2, 9)
m = = = 5 , then
y = 5x + c ← is the partial equation
To find c use any ordered pair from the table and substitute into the partial equation.
Using (3, 14 ) , then
14 = 15 + c ⇒ c = 14 - 15 = - 1
y = 5x - 1 ← equation of line
Yes, it can both arithmetic and geometric.
The formula for an arithmetic sequence is: a(n)=a(1)+d(n-1)
The formula for a geometric sequence is: a(n)=a(1)*r^(n-1)
Now, when d is zero and r is one, a sequence is both geometric and arithmetic.
This is because it becomes a(n)=a(1)1 =a(1). Note that a(n) is often written an
It can easily observed that this makes the sequence a constant.
