Option (c) is the correct answer
The equation y = -5x + 6 is represented by the given table i.e.
x -2 -1 0 1 2
y 16 11 6 1 -4
Given, a table
x -2 -1 0 1 2
y 16 11 6 1 -4
Now, we have to find the equation of the line, satisfying the given values
As, the equation
y = -5x + 6 satisfying the given set of values,
So, the equation y = -5x + 6 is represented by the given table.
Hence, the equation y = -5x + 6 is represented by the given table.

Hope this helps :D
X = amount of 50% solution
y = total amount after mixing
Note that the amount of alcohol in the 20% solution is 80 (0.2) = 16 oz.
We have 2 unknowns, so we need 2 equations:
first, we can write the equation for the total volume:
y = x + 80
next, apply the percentages to get an equation for the amount of alcohol:
0.4 y = 0.5 x + 16
Finally, solve the pair of equations (in this case, by substitution of the 1st into the second:
0.4 (x + 80) = 0.5x + 16
0.4 x + 32 = 0.5X + 16
rearrange and combine like terms:
0.1x = 16
x = 160
from the 1st equation:
y = 160 + 80 = 240
