What are the ordered pairs?

i cant see the lines clearly, soo all i can say is that:

- x is the horizontal line, y  is vertical

- quadrant I all positive

- quadrant II x negative, y positive

- quadrant III all negative

- quadrant y positive, y negative

- for every line the point passes, it counts as 1

- each point does not have a certain order to go in the chart

sorry, but this is the best i can do for now! make sure your pictures are clear next time :D

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
