Answer:
12/13
Step-by-step explanation:
m=(-6-6)/(-7-6)=-12/-13=12/13
Answer: A
Solution: To find the mean (average) of a data you add up all the data given and divide it by the amound of seperate data there is i.e there are 4 boys, boy a is 1.3m high, boy b is 1.5m high, boy c is 1.1m high and boy d is 2m high. To find the mean(average) you add up all the data (height) 1.3m + 1.5m + 1.1m + 2m = 5.9m, 5.9 is the total, to find the mean you divide the total by the amount of values (boys), there are 4 boys so you do 5.9/4 = 1.475m, so the mean is 1.475m
Basically All the data (regions) added up is 65,000 and there are five regions (values) so you divide 65,000 by 5 which is 13,000
A(-7,4) and B(0,6);
A(x₁,y₁) and B(x₂,y₂)
Equation form : y =mx+b
1st Calculate the slope m:
m=(y₂-y₁)/(x₂-x₁) = (6-4)/(0+7), m = 2/7
the equation becomes: y= 2/7.x +b
2nd Calculate b. to that end you plug any coordinates (either A or B) in the equation y=2/7.x + b:
Let's say I selected B(0,6)
6=2/7(0) +b and b =6
The final equation : y =(2/7).x + 6
