Algebra.Com's Answer #132315 by Mathtut(3670)![]() ![]() ![]() You can put this solution on YOUR website! remember if you have two points you can find the equation of the line. First find the slope which is m= change in y divided by change in x \n" ); document.write( ": \n" ); document.write( "X Y \n" ); document.write( "-2 -6 \n" ); document.write( "-1 ? \n" ); document.write( "0 ? \n" ); document.write( "1 18\r \n" ); document.write( "\n" ); document.write( "18-(-6)/1-(-2)=8........so our slope is 8...now take either of those points and use the point slope formula to get our equation \n" ); document.write( ": \n" ); document.write( "y+6=8(x+2) \n" ); document.write( ": \n" ); document.write( "y+6=8x+16 \n" ); document.write( ": \n" ); document.write( "y=8x+10 \n" ); document.write( ": \n" ); document.write( "now plug in our know values of x to find our y(?) points....I am out of time so I will let you do that \n" ); document.write( " |
