<h3>Answer: The lines are perpendicular</h3>
=================================================
Work Shown:
Use the slope formula to find the slope of the line through the two given points.
m = (y2 - y1)/(x2 - x1)
m = (-4 - (-5))/(6 - (-7))
m = (-4 + 5)/(6 + 7)
m = 1/13
The slope of the line through the two given points is 1/13.
This is not equal to -13, which was the slope of the first line, so the two lines are not parallel.
However, the two lines are perpendicular because multiplying the two slope values leads to -1
(slope1)*(slope2) = (-13)*(1/13) = -1
note: It might help to think of -13 as -13/1 to help multiply the fractions.
Answer:
When it is small & when the sample has things that are different from the population.
Step-by-step explanation:
A small sample has less chance of accurately reflecting a population & too many variables can also negatively influence the study.
X^2 + y^2 - x^2 +y^2
That would be (1x+1y)-(1x+1y)
