Position-time graph for constant velocity

If an object is moving under a constant velocity (`v = 5 m//s`), the Position–time graph will be: Position–time graph for an object under constant velocity. The value of the constant velocity is the slope of the line.
`v = (∆x)/(∆t)` where `∆x = x_f-x_i` `=>v = (x_f-x_i)/(∆t)` `=>`
`x_f = x_i + v∆t`
