Answer:

Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:

In which m is the slope and b is the y-intercept.
Perpendicular lines:
When two lines are perpendicular, the multiplication of their slopes is -1.
Perpendicular to y=1/8x+2
This line has slope 
So, for the line we want to find the equation, we have that:


So

Find the equation of the line through point (1,−5)
This means that when
. We use this to find b. So:



The equation of the line is:

Answer:
12
Step-by-step explanation:
divide 90 by 3 then take that and divide it by 5 then multiply that by 3 then subtract that from the answer of 90 divide by 3
I think it's 12x.
I'm not a 100% sure though, but I hope this helps. =^D
