Ratio means only one thing but I think what you meant was 3 examples of a ratio. In that case three examples would be:
2:3,
2 to 3,
2/3
Answer:

Step-by-step explanation:
Given
The attached graph
Required
Point on the line
The options are not given. So, I will provide general answers.
To do this, we simply write out the coordinates that lie on the line.
Some of them are:
The two points have the same y coordinate, which means that the line is horizontal, which means that the slope is 0.
So, the equation is y=4
Solve for m:
(-3 m)/7 = 12
Multiply both sides of (-3 m)/7 = 12 by -7/3:
(-7 (-3) m)/(3×7) = (-7)/3×12
(-7)/3×(-3)/7 = (-7 (-3))/(3×7):
(-7 (-3))/(3×7) m = (-7)/3×12
(-7)/3×12 = (-7×12)/3:
(-7 (-3) m)/(3×7) = (-7×12)/3
(-7)/7 = (7 (-1))/7 = -1:
(-3-1 m)/3 = (-7×12)/3
(-3)/3 = (3 (-1))/3 = -1:
--1 m = (-7×12)/3
(-1)^2 = 1:
m = (-7×12)/3
12/3 = (3×4)/3 = 4:
m = -74
-7×4 = -28:
Answer: m = -28
