Answer:
The slope of the line is
⇒ B
Step-by-step explanation:
You can find the slope of a line using any two points on the line (x1, y1) 1nd (x2, y2) by using this rule 
<em>Let us use this rule to answer the question</em>
From the attached graph:
∵ The given line passes through points (-1, -2) and (4, 2)
→ That means point (x1, y1) = (-1, -2) and point (x2, y2) = (4, 2)
∴ x1 = -1 and x2 = 4
∴ y1 = -2 and y2 = 2
→ Substitute their values in the rule of the slope above
∴ 
∴ The slope of the line is 
The answer is
-2(u+3)-5u
-2u-6-5u
-3u-6
Answer:
see explanation
Step-by-step explanation:
These are the terms of a geometric sequence with n th term formula
= a 
where a is the first term and r the common ratio
r =
=
= - 
the first term a = 64, hence
= 64
