Algebra.Com's Answer #106467 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Yon can easily see what happens when you notice that the only difference between the two linear equations is y-intercept. \n" ); document.write( "Notice that both equations are in the slope-intercept form: y = mx+b and, in both equations, the slope (m =3) is the same. \n" ); document.write( "So the lines are parallel with the first one crossing the y-axis at y = -2 (b= -2), while the second one crosses the y-axis at y = 6 (b = 6) \n" ); document.write( "Let's confirm this by graphing both equations. \n" ); document.write( "y = 3x-2 (Red line) \n" ); document.write( "y = 3x+6 (Green line) \n" ); document.write( " |
