Answer:
Red and Green are parallel
Black and Blue are perpendicular
Step-by-step explanation:
Parallel lines need to have the same slope. Lines red and green both have a slope of 1/2.
The slopes of two lines that are perpendicular have to be opposite reciprocals, and must be multiplied together to get -1. Line black has a slope of -4, and line blue has a slope of 1/4. Both of them multiplied together equals -1.
Answer:
A. y - 3 = -(x + 5)
Step-by-step explanation:
The general formula for point-slope form is:
, where 'm' is the slope and 
is a point on the line
Using the given graph, you can see that the line is downhill, indicating a negative slope. Starting at the y-intercept of -2 and going down two and over two to the point (2, -4) tells us the overall slope is '-1'. You can also see that there is a point at (-5, 3) on the graph. Using the slope (-1) and the point (-5, 3):
y - 3 = -1(x + 5)

Answer:
The another term for the 4% value is : Margin of error
Step-by-step explanation:
Dr. Cyril conducts a simple random sample of 500 men.
He finds that 23% of them report being unsure of their ability to be good fathers, plus or minus 4%.
Now, the another term for the 4% value is : Margin of error
Means the estimate of father being unsure about his ability would be between 19% and 27%.
When sample size is increased, the margin of error becomes smaller.
