You can put this solution on YOUR website!
let 's start with #2
\n" ); document.write( "#2)By using the slope and y intercept.
\n" ); document.write( "slope is 1/2 and y intercept is 4
\n" ); document.write( "so our first point will be (0,4)
\n" ); document.write( "the slope is rise over run y/x add 2 to x and 1 to y so our next point is (2,5)
\n" ); document.write( "Since it is a line we only need two points.
\n" ); document.write( "Now we turn to #1
\n" ); document.write( "#1)
\n" ); document.write( "So you don't have to have the solution (what ever that is). BTW one linear equation has no solution it is one equation with two unknowns. WE can graph it but there is no unique solution.
\n" ); document.write( "How to graph?
\n" ); document.write( "let x=0 and find y. Well that is the y intercept in this case -3
\n" ); document.write( "(0,-3)
\n" ); document.write( "let y=0 and find x x=3
\n" ); document.write( "(3,0)
\n" ); document.write( "BTW our slope is 1 so when x goes up 1 so does y
\n" ); document.write( "so plot those two points
\n" ); document.write( " \n" ); document.write( "
\n" );
