Answer: bellow
Explanation:
To solve for r, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 8:
1.6 / 8 = (8r) / 8
0.2 = r
Therefore, the value of r is 0.2.
So, Y = rx becomes Y = 0.2x.
To summarize:
Given:
X = 8
Y = 1.6
Using the equation Y = rx, we substitute the values of X and Y:
1.6 = 8r
To solve for r, we divide both sides of the equation by 8:
0.2 = r
Therefore, the value of r is 0.2.
Hence, Y = rx can be written as Y = 0.2x.
