Ineed with finding the coordinates on the graph for this question. plz !

Plug (x,y) = (1,19) into the first inequality
y <= 7*x - 13
19 <= 7*1 - 13
19 <= 7 - 13
19 <= -6
The inequality is false. The number 19 is not smaller than -6, nor is it equal. So the point (1,19) is NOT a solution to the system of inequalities

We don't need to check the other inequality, but let's do so just for the sake of completeness
y > 3*x + 6
19 > 3*1 + 6
19 > 3 + 6
19 > 9
this inequality is true, but again it doesn't matter since the first one is not true

Overall, the point (1,19) is not in the solution set

What are the following algebraic equations. you need to post those if you want the answer
