Answer: 5/7</h3>
Explanation:
I'm assuming the equation is 
which is the same as writing y = (5/7)x.
If so, then the constant of proportionality is the fraction out front: The value 5/7 is the coefficient of the term (5/7)x.
All direct proportion equations are of the form y = kx, where k is the constant of proportionality. Another example would be y = 12x and this time k = 12.
Answer:
the slope is 0
Step-by-step explanation:
We can see by reading the coordinates of the points that they have the same y coordinate -7 so we can tell from the beginning that the slope is 0 because the line going trough the points will NOT go up or down will STAY FLAT at -7.
OR we can actually calculate the slope
The slope of a line in general is m = (y2-y1)/(x2-x1)
The slope of the line the line that passed through the points
(x1 = 1, y1 = -7) and (x2 = 10, y2 = -7) is
m = (-7- -7) / (10-1) =
m = (-7+7)/(10-1)
m = 0/9
m =0
The slope 0 tells us that the two points are on a horizontal line.
