For this case we have the following equation, in a linear way:

This expression can be written in the form 
Where "m" is the slope and "b" is the cut point with the y axis.
Rewriting the given expression we have:

Thus, the slope is 3 and the cut point is -5.
To graph, we must find two points through which the line passes, so, we perform the following steps:
Step 1:
We do 

Thus, the point 
Step 2:
We do


Thus, the point 
Answer:

Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(2, -1)
Equation Form:
x= 2, y= -1
The hypotenuse needs to be longest side but with inequalities it is more complicated so I am pretty sure you can not have those lengths on the triangle.
Might wait for a more qualified person to answer though, but that is my thought on it..
