I got this prescription at an eye-checking machine. I feel like my left eye is really bad and doesn’t see well in the distance. What do the results mean exactly?

Negative numbers mean nearsighted while positive numbers mean farsighted. The numbers themselves are called the “diopter”, which is the measure of the optical power of a lens. So, a 1.50 diopter lens has greater optical power than a 1.00 diopter lens. The numbers on your sheet indicate that you are slightly nearsighted, which explains your difficulty seeing things further away.
