2y+4x=12
Move 4x to the other side as a negative number
2y=-4x+12
Divide all terms by 2
y=-2x+6
Now, in order for two lines to be perpendicular, their gradients have to multiply obeyed to get -1 (let a be the gradient of the given line and let b be the gradient of the line we're trying to find)
So, we do -2*b=-1
so, b is equal to 1/2
Now, we are given a coordinate so we substitute it in y-y1=m(x-x1)
y-1=1/2(x-8)
Expand brackets
y-1= 1/2x-4
Take -1 to the other side as a positive number
y=1/2x-3
So, the equation of the line is y=1/2x-3
square root(-108) - square root(-3) =8.66025404 i

Answer:
The slope is 0.5
Step-by-step explanation:
use the slope formula
x1 y1 x2 y2
( -4 , 5 ) ( 1 , 7.5 )
y2 - y1
----------
x2 - x1
