How do i find an equation for velocity given the following data?
t: 0 | 2 | 4 | 6
v: 39.2 | 349.6 | 660 | 970.4

I know that velocity is change in distance over change in time, but does that really even mean anything for this? Do i still do the same things as usual when finding the slope of a line, aka find the slope and y intercept and plug it into y=mx+t? I dont think so because its not linear.
So I went ahead and calculated change in v over change in t and I got 155.2 every time, so does that mean it is linear? So

It was an online quiz and I put in just v(t) = 155.2x and it said it was wrong. Its picky about how stuff is submitted so it may just be it didn't like how I put it in or it was totally wrong
