Answer:
x = - 5
Step-by-step explanation:
Given
f(x) = - 4x - 10 and f(x) = 10, the equate right sides, that is
- 4x - 10 = 10 ( add 10 to both sides )
- 4x = 20 ( divide both sides by - 4 )
x = - 5
Given equation of the line ,
Simplify ,

Transpose terms to RHS ,
Divide both sides by 5 ,
Now we know the slope intercept form of the line as
we have ,
As we know that the slope of all parallel lines are same . Henceforth ,
To find the percentage,here's what we can do:

The percentage would then be:
=63/420×100%
=3/20×100%
=0.15×100%
=15%
Therefore the answer is 15%.
Hope it helps!
