Answer:
Step-by-step explanation:
Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1)
so it would be
11-(-1)/12--4)
which would be
12/16
to simplify that it is 3/4
Answer:
Surveying a sample would be valid if the population contains a diverse group of people.
I believe its 45.
Its hard to explain but what I can say is if you subtract the percentage with the total of the skins you would subtract what you had from there and then you would have 45.
That both (along with the mean) help the data be described the data's spread, which can be the slope if only two points.
