-0.6
Step-by-step explanation:
The gradient is equal to the change in y divided by change in x. So:
- change in x is 10-5=5
- change in y is 10-13=-3
Therefore, -3/5=-0.6
<u><em> slope of a line = (y2-y1)/(x2-x1)</em></u>
Answer:
3 m/s/s
Step-by-step explanation:
F = ma
28 = 4m
m = 7
m is constant throughout
