With 51 gallons of fuel in its tank, the airplane has a weight of 2321.3 pounds. What is the weight of the plane with 79 gallons of fuel in its tank? The slope is 6.3.
\n" ); document.write( ":
\n" ); document.write( "Using the slope intercept form mx + b = y
\n" ); document.write( "Where
\n" ); document.write( " m = 6.3
\n" ); document.write( " x = 51 (fuel)
\n" ); document.write( " y = 2321.3 (total weight, plane & fuel)
\n" ); document.write( " b = weight of the plane alone
\n" ); document.write( ":
\n" ); document.write( "6.3(51) + b = 2321.3
\n" ); document.write( "321.3 + b = 2321.3
\n" ); document.write( "b = 2321.3 - 321.3
\n" ); document.write( "b = 2000 lb is the weight of the plane
\n" ); document.write( ":
\n" ); document.write( "y = 6.3x + 2000, is the equation
\n" ); document.write( "x = 79
\n" ); document.write( "y = 6.3(79) + 2000
\n" ); document.write( "y = 497.7 + 2000
\n" ); document.write( "y = 2497.7 total weight with 79 gal of fuel \n" ); document.write( "
\n" );
