Answer:
No.
Step-by-step explanation:
I used a graphing tool to graph [tex]5x+15y=19[/tex]. (2,1) does not lie on the line. See the picture attached for the graph.
Another way to check this is to substitute x and y for 2 and 1:
[tex]5(2)+15(1)=19\\\\\left \{ {{5*2=10} \atop {15*1=15}} \right.\\\\10+15=19\\\\\boxed{25\neq19}[/tex]
(2,1) would not lie on the line that has he equation of 5x+15y=19 .
