Hi.
I believe the formula for R when you have the voltage and current is:
V/I = R
Plugging in the numbers:
220/4 = 55
The answer is the second option, 55.
Neither.
Parallel lines have the same slope.
Perpendicular lines have negative reciprocal slopes.
Rewriting the 2nd equation to solve for y,
You get:
Y=1/5x + 1/2
The first equation slope is negative, and the second is positive. However, the second slope is 1/5, and not 5/1 - which would be the negative reciprocal of (-1/5)from the first equation.
Hope that helps!
