Answer #1

Simple linear regression is a statistical method for obtaining a formula to predict
values of one variable from another where there is a causal relationship between the
two variables.

When we release the mobile on the inclined air rail, the formula of speed is

V=V0 +at

Where, V0 is initial speed(constant), a is acceleration(constant), and t is time (variable).

Thus is similar to the line equation

y= mx+c

Thus speed depends upon time linearly, thus inclined air rail is necessary to fit linear model of speed.

Answer: b.we release the mobile on inclined air rail
