Answer:
Slope intercept form:- An equation of line is in the form of y =mx +b .....[1] ; where m is the slope and b is the y-intercept.
Consider any two point from the table i.e,
(1, -2) and (2 , -6)
Calculate first slope of these points:
Slope(m) =
then;
then; substitute the value of m in [1]
Equation of line is;
......[2]
Now, substitute any coordinate point from the table i.e (3 , -10) in [2] to solve for b;
-10 = -4(3) +b
-10 = -12 +b
Add both sides 12 we get;
-10 + 12 = -12 +b +12
Simplify:
2 = b
Equation of line is; y = -4x+2
Therefore, the slope intercept form of the function describe by the given table is;
y = -4x +2

Step-by-step explanation: multiply all numbers to get your answer
hence,
65=5(1-3^n)/1-3
( multiply by -2 on both sides )
130=5(1-3^n)
26=1-3^n
27=3^n
from here, you can use lg to solve for n.
lg 27 = lg 3^n
lg 27 = n lg 3
n = lg 27 ÷ lg 3
hence, n = 3
