Algebra.Com's Answer #475787 by wilft1(217)![]() ![]() You can put this solution on YOUR website! easiest way to find the intercept for either x or y is to simply make it a zero in the equation, example\r \n" ); document.write( "\n" ); document.write( "x-3(0)+6=0 then just solve for x, which in this case will be x = 6\r \n" ); document.write( "\n" ); document.write( "so you have your first intercept, (6,0)\r \n" ); document.write( "\n" ); document.write( "lets find the x intercept, remember, replacing x with zero\r \n" ); document.write( "\n" ); document.write( "0-3y+6=0 in this case, y = 2\r \n" ); document.write( "\n" ); document.write( "we now have our y intercept (0,2)\r \n" ); document.write( "\n" ); document.write( "now, to find our slope, remember slope intercept form y-mx+b where m represents the slope\r \n" ); document.write( "\n" ); document.write( "m = y2-y1 \n" ); document.write( ",,,,,,----- \n" ); document.write( ",,,,,,x2-x1\r \n" ); document.write( "\n" ); document.write( "cant really use our intercepts for this because you would be subtracting 0 from 0, i just tried, so i'll use 2 other points that i plotted out(6,4)and(9,5) \n" ); document.write( ",,,5 - 4,,,,,, 1 \n" ); document.write( "m=------ = -- \n" ); document.write( ",,,9 - 6,,,,,, 3\r \n" ); document.write( "\n" ); document.write( "theres your slope, 1/3\r \n" ); document.write( "\n" ); document.write( "for every 3 you go right, you go up 1 \n" ); document.write( " |
