The formula for f(x) is f(x) = 1/4(8 - 5x)
How to write a formula for f(x)?
The equation of the function is given as:
-5x - 4y = -8
Add 5x to both sides of the equation
-4y = 5x - 8
Divide both sides both the equation by -4
y = -1/4(5x - 8)
Rewrite the above equation as:
y = 1/4(8 - 5x)
Express the above equation as a function
f(x) = 1/4(8 - 5x)
Hence, the formula for f(x) is f(x) = 1/4(8 - 5x)
