There are 18 different possible values for N.
Explanation: 180=2x2x3x3x5
Therefore there are 3x3x2 possibilities.
The answer is
Option A and B
Basically, they're asking you to find the slope of the given line, as well as finding how far apart each points are from one another, horizontally and vertically.
Remember, horizontal goes this way (------) and vertical goes this way (I)
(I)
(I)
a) Horizontal distance : -2
Vertical distance : 3
b) Slope :
Remember, slope is rise over run.
So, rise = vertical distance, and run = horizontal distance.
So, our slope is : -3/2

x - y = 8
Add y to both sides
x = 8 + y
4x + y = 4
Substitute the value of x from the first equation in
4(8 + y) + y = 4
Simplify and solve
32 + 4y + y = 4
32 + 5y = 4
5y = -28
y = -5.6
Now put that value of y into the first equation
x = 8 + (-5.6)
x = 2.4
