This looks like the general equation equation of motion in a gravitational field,
y = Yo + Vo t + (1/2) g t^2
The initial velocity is Vo = 3.1 m/s.
It appears to be an equation for vertical position (measured positive downward) at time t = 0.43 s. 0.92 m is the position at that time.
The units of the "9.8" should be m/s^2, not m/s.
You seem to have left out Yo, the term for the position at t=0, because the two sides of your equation are not equal. Do the numbers.
