Do you mean X is A.
BTW did you get the question from Khan Academy.
A. if you solve for y, then you get y=2x+18, and that is not direct variation, so it is not
B. It is direct variation since you only have a slope and the line passes through the origin so it is direct variation
C. If you solve for y, you get y=1/3x. and that is direct variation because the line passes through the origin.
D. That is not direction variation,because that is inverse variation.
So it is B, C
Answer:
59%
Step-by-step explanation:
19/32= 59.375 so rounded would be 59 :)
The slope of the line that passes through the pair of point (5, 7), (2, 1) is 2
<em><u>Solution:</u></em>
Given that line that passes through the pair of point (5, 7), (2, 1)
To find: slope of the line
<em><u>The slope of line is given as:</u></em>
For a line passing through two points 
and 
slope is given as:
Here in this problem,
<em><u>Substituting the values in above formula,</u></em>
Thus the slope of given line is 2
The answer to this question is z=-5
