Pls me asap for number (the one with a data table next to it) u random answers gets reported and moderated)

No,2

It's a linear function : f(x) = mx + b OR y = m.x + b   (since f(x) = y.

Let's calculate the slope m→    m=(y₂-y₁)/(x₂-x₁)

The pair of the 1st data is (4 ; 7.5)
The pair of the 2nd data is (6 ; 9)

Then m = (9-7.5)/(6-4) → m = 0.75 (you can verify it with any other pair).

y = 0.75x + b. Now let's calculate b (which is the y-intercept) by plugging in any pair, let's take the last one (10,12)

12 = (0.75)(10) + b → b= 12 - 7.5 → b = 4.5

The equation becomes y = 0.75x + 4.5 OR f(x) = 0.75x +4.5
