You can put this solution on YOUR website!
graph each system of equations on the same set of axes.name the point of intersection.y=3x+1 y=x-1
\n" ); document.write( "--------------------------------
\n" ); document.write( "Graph equation y = 3x + 1
\n" ); document.write( "You need two points:
\n" ); document.write( "If x = 0, y = 3*0+1, so y = 1
\n" ); document.write( "If x = 1, y = 3*1+1, so y = 4
\n" ); document.write( "Plot the two points (0,1) and (1,4)
\n" ); document.write( "Draw a line thru them to get:
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C3x%2B1%29\"$
\n" ); document.write( "----------------------------
\n" ); document.write( "Graph equation y = x-1
\n" ); document.write( "You need two points:
\n" ); document.write( "If x = 0 , y = 0-1, so y = -1
\n" ); document.write( "If x = 1 , y = 1-1, so y = 0
\n" ); document.write( "Plot the two points ( 0,-1) and (1,0)
\n" ); document.write( "Daw a line thru them to get:
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2Cx-1%29\"$
\n" ); document.write( "-------------------------------------------
\n" ); document.write( "Now graph both of those line on the same set of axes to get:
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C10%2C3x%2B1%2Cx-1%29\"$
\n" ); document.write( "---------------------------------------------
\n" ); document.write( "The point of intersection is the solution for the set of equations.
\n" ); document.write( "It is (-1,-2)
