1) Assume that in 2014 the number of vehicle sales in theUkraine was 232 thousand and in 2019 it was 108 thousand. a)determine the average rate of change (slope) in the number ofvehicle sales from 2014 to 2019. Include the units. b) if x is thenumber of years since 2014 and z(x) is the number of vehicles sold,write the equation of the line through these two points. c)Assuming z(x) is a linear function, use the equation to predict thenumber of vehicles sold in 2022.
2) A cyclist traveled 12 kilometers per hour faster than anin-line skater. In the time it took the cyclist to travel 52.5kilometers, the skater had gone 22.5 kilometers. Determine thespeed of the skater.
