You can put this solution on YOUR website!
First write the equation of the line in slope intercept form by solving the equation for y.
3x+-+4y+=+7

+-4y+=+-3x+%2B+7

Divide both sides by -4:

+%28-4y%29%2F%28-4%29+=+%28-3x%29%2F%28-4%29++%2B+7%2F%28-4%29
+y+=+%283%2F4%29x++-+7%2F4

Slope = m = coefficient of x = 3%2F4
