Answer:
slope
point-slope form
correlation
Step-by-step explanation:
If you have a line and you know the coordinates of a point on the line, (x1, y1); and you know the <u>slope</u>, m, you can write the equation of the line in <u>point-slope form</u>, y - y1 = m(x - x1). 2 variable data whose point pattern can be represented best by a line is said to have a linear <u>correlation</u>.
The slope, meaning how steep a line is, is represented by the variable m for linear equations.
y - y1 = m(x - x1) is point-slope form, one type of linear equation to represent a straight line. (There is also standard form and slope-intercept form).
Correlation is the relationship between things, like 2 variable data.

I believe the correct answer is A
Step-by-step explanation:
Answer: (C) the 2633 viewers who phoned in.
Step-by-step explanation:
In statistics , a sample is a countable subset of a large population that represents the entire population.
Given : A television station is interested in predicting whether or not voters are in favor of an increase in the state sales tax.
It asks its viewers to phone in and indicate whether they support or are opposed to an increase in the state sales tax in order to generate additional revenue for education.
Of the 2633 viewers who phone in, 1474 (55.98%) are opposed to the increase.
i.e. 1474 out of 2633 viewers opposed to the increase.
Clearly , 2633 viewers are representing the entire population of viewers.
Hence, the sample obtained is the 2633 viewers who phoned in.

A. When you add to negative numbers, it is always negative. A positive + a positive is positive. In D, the answer is always 0. 1 + -1 is 0. In C, it varies. The bigger number not including the negative sign is the sign the number has. For example, -6 + 5 = -1. 6 is bigger than 5. You subtract the smaller number from the bigger number and that is the answer. You would then tack on the negative sign because it is -6, and 6 is bigger than 5.
