For this case we have to by definition:
If two lines are parallel then their slopes are equal.
If two lines are perpendicular then the product of their slopes is equal to -1.
We have the following equations:
We manipulate the equation to convert it into the slope-intersection form 
Where:
m: It's the slope
y: It is the cut-off point with the y axis.
So:
From the second equation given we have:
We manipulate:
It is observed that the slopes are equal, so the lines are parallel,
ANswer:
The lines are parallel.
Answer:
The value of AB is 14
Step-by-step explanation:
When we say a set of points are collinear, what we mean is that those points are on the same straight line i.e they lie on a straight line.
Now B is between A and C
Since B is between A and C
Then mathematically;
AC = AB + BC
18 = AB + 4
AB = 18-4
AB = 14
Answer:
No solution
Step-by-step explanation:
3 = 5 is a false statement
So no solution
