find the slope and the y intercept of the line
\n" ); document.write( "9x = 2y + 8 ? what is the slope
\n" ); document.write( "Solve for Y:
\n" ); document.write( "y = (9/2)x-4
\n" ); document.write( "slope = (9/2)
\n" ); document.write( "----------------
\n" ); document.write( "2)FIND THE SLOPE- (3,4) AND (9, -10)? SLOPE M IS WHAT
\n" ); document.write( "slope = (-10-4)/(9-3) = -14/4 = -7/2
\n" ); document.write( "---------------------------\r
\n" ); document.write( "\n" ); document.write( "3)DETERMINE WHETHER THE GRAPH OF THE TWO EQUATION ARE PERPENDICULAR
\n" ); document.write( "Y=2X- 3
\n" ); document.write( "slope = 2
\n" ); document.write( "------------
\n" ); document.write( "6Y= 5-X
\n" ); document.write( "slope = (-1/6)
\n" ); document.write( "----------------------
\n" ); document.write( "The product of the two slopes is not -1, so the lines are not perpendicular.
\n" ); document.write( "---------------------------------------
\n" ); document.write( "3)FIND AN EQUATION OF THE LINE CONTAINING THE GIVEN PAIR OF POINTS
\n" ); document.write( " (-2, -8) AND (-9, -3)
\n" ); document.write( " WHAT IEQUATION OF THE LINE IS Y
\n" ); document.write( "slope = (-3--8)/(-9--2) = 5/-7 = -5/7
\n" ); document.write( "Y= mx + b and you know y,x and m: solve for \"b\" as follows:
\n" ); document.write( "-3 = (-5/7)(-9)+b
\n" ); document.write( "-3 = (45/7) + b
\n" ); document.write( "-21/7 = 45/7 + b
\n" ); document.write( "b = -66/7
\n" ); document.write( "---------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "y = (-5/7)x -(66/7)
\n" ); document.write( "==========================
