Answer:
The slope is 9.
Step-by-step explanation:
Answer:
- 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (1, 1) ← 2 points on the line
m =
=
= 5
Given a line with slope m then the slope of a line perpendicular to it is
= -
= - 
Answer:
Step-by-step explanation:
Find the slope of the line
(x₁ , y₁) = (6 , 8) & (x₂ , y₂) = (0 , 5)

m = 1/2 ;(x₁ , y₁) = (6 , 8)
y - y₁ = m(x - x₁)
