Answer: Slope is the measure of the steepness of a line. It can be calculated with the equation rise/run or change in y/change in x.
Step-by-step explanation:
Answer:
(-2 , 2)
Step-by-step explanation:
A(-8 , 2) = (x1 , y1)
B(4 , -2) = (x2 , y2)
midpoint = (x1 + x2/2 , y1 + y2/2)
=(-8 + 4/2 , 2-(-2)/2)
=(-4/2 , 2+2/2)
(-2 , 2)
(3 , 7) = (x1 , y1)
(9 , 2) = (x2 , y2)

Answer:
B
Step-by-step explanation:
Variance can be said to be a measure of dispersion for a random sample.
Variance = pq/n
When given the variance, we can find the standard deviation.
Standard deviation = √variance
= √pq/n
We can't tell from the information given. What we do know is
P(A ∩ B) = P(A|B) P(B)
We're given the conditional probability but not the probability of the conjunction.
If we were told P(A|B)=0.8 and P(A ∩ B)=0.12 we could conclude
P(B)=P(A ∩ B)/P(A|B) = 0.12/0.8 = 0.15
but that wasn't the problem asked.
Find the gradient/slope of Line A:
(3-2)÷(-1-4)
=-0.2
Therefore, the gradient/slope of line B is 5
Using the equation y-y1=m(x-x1) we can find the equation of line B
y-7=5(x-3)
y= 5x-8
Sub in a random value for y (eg. y=2)
2=5x-8
5x=10
X=2
so (2,2)
