The required equation is:
Option C is correct.
Step-by-step explanation:
The proportional relationship can be found using the equation:
where x and y are the points and k is the constant of proportionality.
We need to find k.
From the graph given, we can locate points x and y:
x=5, y= 35 then k would be:
x=10, y=70 then k would be:
For each values of x and y, the constant of proportionality k is 7
So, the required equation is:
Option C is correct.

Answer
-8 r > 0
Step-by-step explanation:
you know that r is less than or equal to -8, so you write that, and then you know that r is also greater than 0, so then you add that to it, and then you have the answer. r will be in the middle because it is the range of what are can be.
Answer:
y = 1/4 x - 1/2
Step-by-step explanation:
Remark
The general equation for a line is y = mx + b
You know that m = 1/4. The problem is what do you do about (2,0)?
Solution
y = 1/4 x + b Let x = 2 when y = 0
0 = 1/4 * 2 + b multiply 2 * 1/4
0 = 1/2 + b Subtract 1/2 from both sides
b = - 1/2
equation y = 1/4 x - 1/2
