Someone please do this and show work

1) 1/4

2) 3/5

Step-by-step explanation:

1) The rate of change is basically the slope, and you can find the slope by doing:

change in y/change in x

I started with the point (0,-2) because it's on the line

It goes up 1 and left 4 to get to the second point on the line

So change in y/change in x = 1/4 (this is the rate of change)

2) This is basically the same thing, but you need to do some subtraction.

Change in y = -9-(-3) = -6

Change in x = -5 - 5 = -10

Change in y/change in x = 3/5 (this is the slope or rate of change)

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
