Answer 1

Sure, what's your question?

Answer 2

hint:
we can write this:
\[\large y = ax + b\]
now we have to determine the coefficients a and b

Answer 3

for example if I substitute your first pair (x,y)
we get:
\[\large 2 = 2a + b\]
whereas if I substitute the second pair, I write:
\[\large 5 = 4a + b\]
so we have to solve this system:
\[ \large \left\{ \begin{gathered}
2 = 2a + b \hfill \\
5 = 4a + b \hfill \\
\end{gathered} \right.\]

Answer 4

do you know how to solve that system?
