Line joining two points
The computer gives you 2 points. Your job is to find the slope and
y-intercept of the line joining them.
Length of a line
The computer gives you 2 points and you have to find the length of the
In these problems, you are given either the slope or the y-intercept
of the line and a point on it. The object of the exercise is to find the
missing variable and put the equation together.
You are given a point on the line and the equation of a line that is either
parallel or perpendicular to the line passing through the point. Your job is
to find the equation of that line.
Easy intersection of 2 lines
In these problems, you have to find the point where the two lines meet.
This is the easy one because the co-ordinates are nice whole numbers.
Brave intersection of 2 lines
I suppose it is possible that the co-ordinates of the intersection point in
these problems might be whole numbers. It depends on the mood the
computer is in.
