Slope: $(Y^2-Y^1)/(X^2-X^1)=(rise)/(run)$

$(4-5=-1)/(1-(-2)=1+2=3)=(-1)/(3)=-(1)/(3)$

Slope is -1/3

Answer is -1/3

Hope this helps!

Can someone explain to me what chromosomes are, and also explain briefly and understandably grade 10/ 10th grade biology term 1 with genetics and stuff? Thanks heaps if you can :D

Answers

Chromosomes are what the mother and father donate to the fetus in order to compose your basic genetics

The father gives half which is 25 and the mother gives 23

The reason for this is when a baby is being created it is given a gender. That gender is either boy or girl the boy has an added chromosome at the near middle of gestation and the girl lacks that last chromosome so thats why the father gives more chromosomes than the mother

Which of these could NOT be a measurement of speed? A. 10 m/s B. 35 mi/s C. 5 km/h north D. 1,000,000 mm/h

Answers

Answer:

C. 5 km/h north

Explanation:

Speed is the rate at which an object changes position, and it is measured in meters per square seconds. The formula or equation used in calculating speed is distance divided by time. The distance traveled is always in meters and time is always in seconds to get the speed it will be one meter per second. Speed doesn’t specify the direction at which an object will travel. Hence the answer is C. 5Km/hr north
