I’m not sure if I’m correct and especially with the table !

Answer:
No, it would not because the point (3, 15) is not on the line.
Explanation:
Given the below equation of the line;
[tex]y=5x-2[/tex]To be able to determine if the point (3, 15) is on the above line, let's substitute x = 3 into the above equation of the line and find the corresponding value of y;
[tex]\begin{gathered} y=5(3)-2 \\ y=15-2 \\ y=13 \end{gathered}[/tex]From the above, we can see that the point (3, 13) will be on the said line and not point (3, 15)
