Graph m%3E-3 on a number line:
MSP366216d5id9hadae20d500002921e0eba1idag8b

2.
given: (1,4)
3x%2B4y%3E19+........substitute given x=1 and y=4
3%2A1%2B4%2A4%3E19+
3%2B16%3E19+
19%3E19+ -> false, so given point is not a solution


7x-2y%3E-1....substitute given x=1 and y=4
7%2A1-2%2A4%3E-1
7-8%3E-1
-1%3E-1-> false, so given point is not a solution
none of the inequalities above have (1,4) as a solution

Notice that the graph shown in the second line of the post by  @MathLover1 is  INCORRECT.

The correct graph is shown below m > -3 

     -------|-------|-------(=======|=======|=======|=======|===

           -5      -4      -3      -2      -1       0        1
