To determine which ordered pairs represent points on the graph of the equation \( x = \frac{3}{5}y \), we can rearrange this equation to express \( y \) in terms of \( x \):

\[ y = \frac{5}{3}x \]

Now we can check each ordered pair (x, y) to see if it satisfies the equation \( x = \frac{3}{5}y \).

  1. For the point \((-5, 3)\): \[ -5 = \frac{3}{5}(3) \Rightarrow -5 = \frac{9}{5} \quad \text{(False)} \]

  2. For the point \((-3, -5)\): \[ -3 = \frac{3}{5}(-5) \Rightarrow -3 = -3 \quad \text{(True)} \]

  3. For the point \((3, 5)\): \[ 3 = \frac{3}{5}(5) \Rightarrow 3 = 3 \quad \text{(True)} \]

  4. For the point \((-5, -3)\): \[ -5 = \frac{3}{5}(-3) \Rightarrow -5 = -\frac{9}{5} \quad \text{(False)} \]

  5. For the point \((5, -3)\): \[ 5 = \frac{3}{5}(-3) \Rightarrow 5 = -\frac{9}{5} \quad \text{(False)} \]

  6. For the point \((3, -5)\): \[ 3 = \frac{3}{5}(-5) \Rightarrow 3 = -3 \quad \text{(False)} \]

The ordered pairs that satisfy the equation \( x = \frac{3}{5}y \) are:

  • \((-3, -5)\)
  • \((3, 5)\)

So the correct answers are:

  • (-3, -5)
  • (3, 5)
