Algebra.Com's Answer #533096 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! \"Which of the following equations describe the line shown below?\"(3,2)and(-1,-4) \n" ); document.write( "I've plotted it on this site hoping it would help me get a better idea of the question, https://www.mathway.com/ \n" ); document.write( " I was also wondering if you could explain what happens to x2 and y2, you see i arranged them in \"slope formula\" as my teachers call it (although i know there are many different names for it) and i understand where y1 and x1 go,but i don't understand what happens to x2 and y2.
