Answer:
b hope this helps
Step-by-step explanation:
Option 1. The equation that represents the direct variation that exists between a and b is b = –a.
<h3>How to find the direct variation here</h3>
The direct variation is of this form y ∝ x
This gives the equation
y = kx
The constant is k
From our question we have
b ∝ a so b = ka
b = 
a = 
Remember that b = ka

This would cancel out to
1 = -k
or k = -1
Hence the equation would be written as
b = -a

Answer:
The answer is
<h2>10 units</h2>
Step-by-step explanation:
The distance between two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(-2,1) and (-8,9)
The distance between them is

We have the final answer as
<h3>10 units</h3>
