Answer:
Step-by-step explanation:
If a line is passing through the point (a,b) and has a slope m, then the equation of the line in point-slope form is given by :-
Given: A line that includes the point (6, 1) has a slope of 9.
The equation of line in point-slope form:
Hence, the required equation in point slope form:
Answer:
The sum is
Step-by-step explanation:
we know that
The formula of the sum in a geometric sequence is equal to
where
a1 is the first term
r is the common ratio
n is the number of terms
we have
a1=-4, a2=24, a3=-144
Find the value of r (common ratio)
r=a2/a1
r=24/(-4)=-6
so
a1=-1
r=--6
n=6
substitute in the formula
Counterexample:
4 is not a prime number. So, it's false.
