I did one similar yesterday. Follow that method. If you have trouble or want me to check your work, email me via the thank you note.
\n" ); document.write( "----------------------
\n" ); document.write( "write an equation in slope-intercept form of a line containing the points (-8,9)and (-6,-5).
\n" ); document.write( "--------------
\n" ); document.write( "There are 2 ways to do these.
\n" ); document.write( "Method 1:
\n" ); document.write( "Find the slope, m.
\n" ); document.write( "m = diffy/diffx
\n" ); document.write( "m = (-5-9))/(-6-(-8)) = -14/2
\n" ); document.write( "m = -7
\n" ); document.write( "Then use either point:
\n" ); document.write( "y-y1 = m*(x-x1)
\n" ); document.write( "y-9 = -7*(x+8)
\n" ); document.write( "y-9 = -7x-56
\n" ); document.write( "y = -7x-47
\n" ); document.write( "--------------
\n" ); document.write( "--------------
\n" ); document.write( "Method 2:
\n" ); document.write( "|+x +y +1|
\n" ); document.write( "|-8 +9 +1| = 0
\n" ); document.write( "|-6 -5 +1|
\n" ); document.write( "----------
\n" ); document.write( "x*(9+5) - y*(-8+6) + (40+54) = 0
\n" ); document.write( "14x + 2y +94 = 0
\n" ); document.write( "y = -7x - 47
\n" ); document.write( " \n" ); document.write( "
\n" );
