Answer:
perpendicular
Step-by-step explanation:
perpendicular if the product of their slopes is equal to -1
Parallel lines have equal or identical slopes
Answer:
f(x) = x + 4
Step-by-step explanation:
Given
y - x - 4 = 0 ( add x to both sides )
y - 4 = x ( add 4 to both sides )
y = x + 4 ( let y = f(x) )
f(x) = x + 4
The first step to solving this equation is to change the signs on both sides of the equation
y = -
x + 3
Since we don't know what x is but we do know why y is,, we will write our answer with the answer to y and x being left as undefined.
y = -
x + 3, x ∈ R
