Question

question if x and y are in direct proportion and y is 6 when x is 2, find y when x is 5. answer attempt 1 out of 2 y =

Explanation:

Step1: Find the constant of proportionality

Since $x$ and $y$ are in direct - proportion, the relationship is $y = kx$. When $y = 6$ and $x = 2$, we can find $k$ by substituting these values into the equation: $k=\frac{y}{x}=\frac{6}{2}=3$.

Step2: Find $y$ when $x = 5$

Now that we know $k = 3$, we use the equation $y=kx$. Substitute $x = 5$ and $k = 3$ into the equation: $y=3\times5 = 15$.
