Hi there! The answer is A.
[tex]t = 2(s + 2)[/tex]
To get a proper idea of the type of function this formula represents we work out the parenthesis.
Working out the parenthesis can for instance be done using rainbow technique.
[tex]t = 2s + 4[/tex]
We can now see sinilarities between this function an the general function of a line in slope intercept form
[tex]y = mx + n[/tex]
The function t therefore describes a line with slope 2 and y-intercept 4. Therefore the answer is A.
