\n" ); document.write( ": given these two points on a line, write the equation in slope-intercept form:
\n" ); document.write( "(5,-13) and (2,-1)
\n" ); document.write( "i did the coordinate approach and came out with: -1-(-13)/2-5=-4, which is the slope. to find the y=intercept, i took one of the points and did: 2=-4(-1)+b. I came out with 2=4+b. now subtracted 4 from both sides and got: 4-2=4+b-4 which simplifies to:-2=b. so my final equation would read: y=-4x+(-2). is this correct?? \n" ); document.write( "

You can put this solution on YOUR website!
YOU GOT THE SLOPE RIGHT BUT YOU SUBSTITUTED THE WRONG VALUES IN THE EQUATION
\n" ); document.write( "Y=mX+b
\n" ); document.write( "YOU SHOULD HAVE OBTAINED THE FOLLOWING FOR (2,-1)
\n" ); document.write( "-1=-4*2+b
\n" ); document.write( "-1=-8+b
\n" ); document.write( "b=-1+8
\n" ); document.write( "b=7 thus the equation foir this line is
\n" ); document.write( "y=-4x+7 \n" ); document.write( "

\n" );
