Given
The points (2,1) and (-2,-2).
To graph the line that passes through the given points and to find the equation of the line.
Now,
It is given that, the points (2,1) and (-2,-2).
The graph of the line which passes through (2,1) and (-2,-2) is,
Therefore, the equation of the line is,

Then, for (2,1) and (-2,-2), the equation of the line is,

Hence, the equation of the given line is 3x-4y-2=0.
