Answer:
A
Step-by-step explanation:
It is the only one with the correct dots for each number.
Given the ordered pair:
(8, 5)
Let's find the ordered pair that represents a point on the same graph assuming this is a graph of a proportional relationship.
Here, we have:
(x, y) ==> (8, 5)
Since this is a graph of a proportional relationship, let's find the constant of proportionality.
We have:
![K=\frac{y}{x}=\frac{5}{8}](https://tex.z-dn.net/?f=K%3D%5Cfrac%7By%7D%7Bx%7D%3D%5Cfrac%7B5%7D%7B8%7D)
This means when x is 1, y is 5/8.
Thus, the ordered pair that also represents a point on the same graph is:
![(1,\frac{5}{8})](https://tex.z-dn.net/?f=%281%2C%5Cfrac%7B5%7D%7B8%7D%29)
ANSWER:
Answer:
(4, 7) (third answer choice)
Step-by-step explanation:
In the system
y = x + 3
3x + y = 19
the first equation already gives y in terms of x. Thus we can substitute x + 3 for y in the second equation:
3x + (x + 3) = 19, which simplifies to:
4x = 16, yielding x = 4. Substituting 4 for x in the first equation, we get:
y = (4) + 3 = 7.
Thus, the solution is (4, 7) (third answer choice).
