How do you write an equation with the relation
\n" ); document.write( "x 1 2 3 4 5
\n" ); document.write( "y 5 7 9 11 13
\n" ); document.write( ":
\n" ); document.write( "This looks like a linear equation so you only need two sets of coordinates:
\n" ); document.write( "Assign them as follows: x1=1; y1=5; x2=2; y=7
\n" ); document.write( ":
\n" ); document.write( "Find the slope using the slope equation: m = \"%28y2+-+y1%29%2F%28x2+-+x1%29\"
\n" ); document.write( "m = \"%287-5%29%2F%282-1%29\" = \"2%2F1\" = 2
\n" ); document.write( ":
\n" ); document.write( "Use the slope/intercept formula: y - y1 = m(x - x1)
\n" ); document.write( "y - 5 = 2(x - 1)
\n" ); document.write( "y - 5 = 2x - 2
\n" ); document.write( "y = 2x - 2 + 5
\n" ); document.write( "y = 2x + 3
\n" ); document.write( ":
\n" ); document.write( "Substitute the given values for x and see that they equal y \n" ); document.write( "
\n" );
