How do you derive the equation for position vs. time from the velocity vs. time equation? For example let's say the velocity equation is v = 0.17t + -0.43

Question

How do you derive the equation for position vs. time from the velocity vs. time equation? For example let's say the velocity equation is v = 0.17t + -0.43
How would I go about figuring out the position vs. time equation with accurate numerical constants?

Thanks in advance!
