From the table, y varies directly as x. Therefore, the constant of variation is k = 2 and y = 2x.
<h3>How to find a direct variation?</h3>
For direct variation,
y ∝ x
Therefore,
y = kx
where
- k = constant of proportionality
Hence,
(-2, -4)
-4 = -2k
k = -4 / -2
k = 2
(-4, -8)
y = -4(2) = -8
Therefore,
k = 2 and y = 2x

Answer:
-1/11
Step-by-step explanation:
Parallel lines have the same slope, but different y-intercepts. So, if the slope of the green line is -1/11, then the slope of the red line would also be -1/11.
The best way to convert 12.5% into a fraction is to write it as 12.5/100. To get rid of the decimal, simply multiply 12.5/100 by 2, since .5 * 2 is 1. Now you have 25/200.
-1/2x + 2 = -x + 7
-1/2x + x = 7 - 2
1/2x = 5
x = 10
