A simple y v x should show relationship
Suggest you FIRST chose a scatter plot
THEN chose regression based on shape of scatter plot.
You may wish to look separately at different categories, e.g age, sex, occupation/lifestyle if you have thes in seeing data if you can make available via doiprbox ore google drive out similar

Hi Art,
I really appreciate your cooperation with me.
The number of cases is a around 74,000 participants. It is a
cross-sectional national data which was collected randomly.
The objective of this exploratory cross-sectional study is to find the
dose-response association between physical activity (independent) and
quality of life (dependent).
Physical activity variable is as it shows below in minutes/week:
.00
30.00
60.00
90.00
120.00
150.00
180.00
210.00
240.00
270.00
300.00
330.00
360.00
390.00
420.00
450.00
480.00
510.00
540.00
570.00
600.00
630.00
QOL is continuous and ranges from 0-100 (the higher score is better)
