An inverse variation includes the points (2, 3) and (1, n) . Find n. Write and solve an inverse variation equation to find the answer. n = _____

Identify General Form: Given that there is an inverse variation between two variables. Identify the general form of inverse variation. In inverse variation, one variable is directly proportional to the reciprocal of the other. Inverse variation: y = k / xFind Constant of Variation: We know that the points (2, 3) are part of the inverse variation. Use the given point to find the constant of variation k. Substitute 2 for x and 3 for y in y = k / x. 3 = k / 2Solve for k: Solve the equation to find the value of k. To isolate k, multiply both sides by 2. 3 × 2 = (k / 2) × 2 6 = kWrite Inverse Variation Equation: We have found that k = 6. Write the inverse variation equation with the found value of k. Substitute k = 6 into y = k / x. y = 6 / xFind n: Use the inverse variation equation to find n when x = 1. Substitute 1 for x in y = 6 / x. n = 6 / 1 n = 6

Identify General Form: Given that there is an inverse variation between two variables. $\newline$ Identify the general form of inverse variation. $\newline$ In inverse variation, one variable is directly proportional to the reciprocal of the other. $\newline$ Inverse variation: $y = \frac{k}{x}$
Find Constant of Variation: We know that the points $(2, 3)$ are part of the inverse variation. $\newline$ Use the given point to find the constant of variation $k$ . $\newline$ Substitute $2$ for $x$ and $3$ for $y$ in $y = \frac{k}{x}$ . $\newline$ $3 = \frac{k}{2}$
Solve for k: Solve the equation to find the value of $k$ . To isolate $k$ , multiply both sides by $2$ . $3 \times 2 = (k / 2) \times 2$ $6 = k$
Write Inverse Variation Equation: We have found that $k = 6$ . $\newline$ Write the inverse variation equation with the found value of $k$ . $\newline$ Substitute $k = 6$ into $y = \frac{k}{x}$ . $\newline$ $y = \frac{6}{x}$
Find $n$ : Use the inverse variation equation to find $n$ when $x = 1$ . Substitute $1$ for $x$ in $y = \frac{6}{x}$ . $n = \frac{6}{1}$ $n = 6$
