Answer 1

There you go... ☺☺

$if \: the \: point \: lies \: on \: the \: graph \: it \: means \: that \: the \: \\ equation \: is \: satisfied \: with \: x \: and \: y \: value... \\ x = 3 \\ y = 4 \\ 3y = ax + 7 \\ substituting... \\ 3 \times 4 = 3 \times a + 7 \\ 12 = 3a + 7 \\ 5 = 3a \\ > > > > > > > > a = \frac{5}{3} < < < < < < < <$
