HI, a right triangle is a triangle that has a 90 degree angle. the angle look similar to the letter l capitalized L then to complete this you will draw a diagonal line connecting the two points on the 90 angle. I Hope this could help.
If you multiply the first equation by 2, you get the second equation. Consequently, these equations are said to be "depenent", so both describe the same line. Any of the infinite number of points on the line is a solution, so ...
... The system has infinitely many solutions.
