Answer:
5
Step-by-step explanation:
given that x and y are proportional, they can be expressed as y = rx, where r is the proportionality constant. Thus, we can solve for r by doing y/x in any given point.

C. 5/15
First, change 3/7 to have the same denominator as 1/14.
3/7=6/14 because 7•2=14 (denominator) 3•2=6 (numerator)
Next, subtract 1/14 from 6/14.
6/14-1/14=5/14
Answer:

Step-by-step explanation:
The equation in slope-intercept form is given by:

where
is the slope and
is the y-intercept.
The given line passes through so many points. We can use any two these points to find the slope of the line.
The line passes through
and
.
The slope is given by;
.
.
.
The y-intercept from the graph is 
Our equation finally becomes;
