Question 354423: solve the system by graphing. I fthe system is inconsisten and has no solution, state this. If the system if dependent, write the form o the solution for any real number

3x - 2y = 4
-6x + 4y= 7

Solve by graphing:
3x-2y+=+4
-6x%2B4y+=+7 Rewrite in slope-intercept form: y+=+mx%2Bb
3x-2y+=+4 Add 2y to both sides.
3x+=+2y%2B4 Subtract 4 from both sides.
3x-4+=+2y Finally, divide both sides by 2.
%283%2F2%29x-2+=+y or
highlight%28y+=+%283%2F2%29x-2%29
-6x%2B4y+=+7 Add 6x to both sides.
4y+=+6x%2B7 Finally, divide both sides by 4.
y+=+%286%2F4%29x%2B7%2F4 or
highlight_green%28y+=+%283%2F2%29x%2B7%2F4%29

The lines are parallel so there is no intersection and no solution.
