Algebra.Com's Answer #406255 by aaronwiz(69)![]() ![]() ![]() You can put this solution on YOUR website! Hi, my name is Aaron I am in 10th grade and im in honors trig/pre-calc. \r \n" ); document.write( "\n" ); document.write( "Start by finding the slope, let start by writing it in point slope form, (Y2-Y1)=m(X2-X1). You will use this form and similar forms more and more as you advance in math, such as with conics, abs-value graphs, and square root graphs. so it helps to start using it now. Although this problem can just as easily be completed using slope-int form \r \n" ); document.write( "\n" ); document.write( "Start by finding two point where the line passes through. (0,50),(4,150)\r \n" ); document.write( "\n" ); document.write( "plug these points into the equation, to solve for m\r \n" ); document.write( "\n" ); document.write( "(150-50)=m(4-0)\r \n" ); document.write( "\n" ); document.write( "100=4m \n" ); document.write( "m=25\r \n" ); document.write( "\n" ); document.write( "Now plug m, back into point slope form and pick any of the two points\r \n" ); document.write( "\n" ); document.write( "(150-y)=25(4-x)\r \n" ); document.write( "\n" ); document.write( "now expand to put it in standard form.\r \n" ); document.write( "\n" ); document.write( "150-y=100-25x \n" ); document.write( "25x-y=-50\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Hope I helped. I would really appreciate your recommendation, their are plenty of other things I could be doing rather then spending time on this site helping people. Good luck! :) \n" ); document.write( " |
