Which equation shows inverse variation? Choices: [[(x)/(36) = y][yx = –74]]

Identify inverse variation: Identify the general form of inverse variation. Inverse variation is characterized by one variable being directly proportional to the reciprocal of another variable. The general form of inverse variation is y = k / x, where k is a constant.Analyze first equation: Analyze the first equation (x) / (36) = y. We need to determine if this equation can be expressed in the form y = k / x. Rewriting the equation, we get y = (x) / (36). This equation suggests that y is directly proportional to x, not inversely proportional, as y increases with an increase in x.Analyze second equation: Analyze the second equation yx = –74. We need to determine if this equation can be expressed in the form y = k / x. By isolating y, we rewrite the equation as y = –74 / x. This equation fits the form y = k / x with k = –74, indicating that y is inversely proportional to x.Determine inverse variation equation: Determine which equation shows inverse variation. Based on the analysis in the previous steps, the equation yx = –74 can be expressed in the form y = k / x and therefore shows inverse variation.
