Which equation has a constant of proportionality equal to 1 ? Choose 1 answer: (A) y=(10)/(11)x (B) y=(7)/(8)x (c) y=(3)/(15)x (D) y=x

Identify Constant of Proportionality: The constant of proportionality in a linear equation y = kx is the value of k, where k is a constant. We need to find the equation where k equals 1.Examine Option (A): Let's examine option (A) y = (10/11)x. The constant of proportionality here is 10/11, which is not equal to 1.Look at Option (B): Now, let's look at option (B) y = (7/8)x. The constant of proportionality here is 7/8, which is also not equal to 1.Consider Option (C): Next, we consider option (C) y = (3/15)x. Simplifying 3/15 gives us 1/5, so the constant of proportionality is 1/5, not 1.Check Option (D): Finally, we check option (D) y = x. Here, the constant of proportionality is 1 because y is directly equal to x without any other factors. This means that for every unit increase in x, y increases by the same amount, which is the definition of a constant of proportionality of 1.

Identify Constant of Proportionality: The constant of proportionality in a linear equation $y = kx$ is the value of $k$ , where $k$ is a constant. We need to find the equation where $k$ equals $1$ .
Examine Option (A): Let's examine option (A) $y = \frac{10}{11}x$ . The constant of proportionality here is $\frac{10}{11}$ , which is not equal to $1$ .
Look at Option (B): Now, let's look at option (B) $y = \frac{7}{8}x$ . The constant of proportionality here is $\frac{7}{8}$ , which is also not equal to $1$ .
Consider Option (C): Next, we consider option (C) $y = \frac{3}{15}x$ . Simplifying $\frac{3}{15}$ gives us $\frac{1}{5}$ , so the constant of proportionality is $\frac{1}{5}$ , not $1$ .
Check Option (D): Finally, we check option (D) $y = x$ . Here, the constant of proportionality is $1$ because $y$ is directly equal to $x$ without any other factors. This means that for every unit increase in $x$ , $y$ increases by the same amount, which is the definition of a constant of proportionality of $1$ .
