The graph of a proportional relationship passes through the points (15,3) and (5,y). Find y.
Idk aka I don't know I'm trying to find out my self

To find the value of y, we need to determine the relationship between x and y. In a proportional relationship, y is directly proportional to x, meaning that their ratio is constant.
To find this constant ratio, we can use the given points on the graph: (15,3) and (5,y). We divide the y-values by their corresponding x-values:
For the point (15,3):
3 / 15 = 0.2
For the point (5,y):
y / 5 = 0.2
Now, we need to solve for y. We can do this by isolating y on one side of the equation. In other words, we need to multiply both sides of the equation by 5:
(y / 5) * 5 = 0.2 * 5
This simplifies to:
y = 1
Therefore, the value of y is 1.
clearly, you need to review what "proportional" means.
y/5 = 3/15
