Your answer would be A. positive linear association.
If we break this phrase down, we first get "positive", which we can see is true here as the graph is ascending towards the top right, that is, going upwards and 'forwards'. This is how we recognise lines with positive slopes, such as 3x or (1/2)x.
The word "linear" means a straight line, you can sort of see the word "line" in it, and so this is also true as the trend line is straight.
I hope this helps!
If n=21 just plug it into the second equation
N+10=_
21+10=_
31=_
31 is the answer
Answer:
1
Step-by-step explanation:
1) First, place the given equation in slope-intercept form (
format) to find its slope easier. Isolate the y:
So, the equation of the line in slope-intercept form is 
. When an equation is in slope-intercept form, the 
, or the coefficient of the x-term, represents the slope. Thus, the slope for the given line would be -1.
2) Lines that are perpendicular have slopes that are opposite reciprocals of each other. We need to find the opposite reciprocal of -1, then.
To find the opposite reciprocal of a number, write the given number as a fraction first -- making -1 be written as 
-- then switch the sign and flip the numerator and denominator. So, the opposite reciprocal of -1 is 1, and 1 is the slope of the perpendicular line.
