Given the equation y = -5x fill in the missing x-value and y-value.

(3, y) y =

(×, 9) x =

1 answer

To find the missing values in the equation \( y = -5x \),

  1. For the point (3, y): \[ y = -5(3) = -15 \] So, for (3, y), \( y = -15 \).

  2. For the point (x, 9): Set \( y = 9 \): \[ 9 = -5x \] To solve for \( x \), divide both sides by -5: \[ x = -\frac{9}{5} = -1.8 \] So, for (x, 9), \( x = -1.8 \).

The completed points are: (3, -15) and (-1.8, 9).
