Find the x- and y-intercept of the line.

–10x – 6y = 120


x-intercept is –6 ; y-intercept is –10.

x-intercept is –12; y-intercept is –20.

x-intercept is –20; y-intercept is –12.

x-intercept is –10; y-intercept is –6.

1 answer

To find the x- and y-intercepts of the line given by the equation \(-10x - 6y = 120\), we can follow these steps:

Finding the x-intercept:

The x-intercept occurs when \(y = 0\).

Substitute \(y = 0\) into the equation:

\[ –10x - 6(0) = 120 \] \[ -10x = 120 \] \[ x = \frac{120}{-10} \] \[ x = -12 \]

So, the x-intercept is \((-12, 0)\).

Finding the y-intercept:

The y-intercept occurs when \(x = 0\).

Substitute \(x = 0\) into the equation:

\[ –10(0) - 6y = 120 \] \[ -6y = 120 \] \[ y = \frac{120}{-6} \] \[ y = -20 \]

So, the y-intercept is \((0, -20)\).

Summary:

  • x-intercept: \(-12\)
  • y-intercept: \(-20\)

Therefore, the correct choice from your list is: x-intercept is –12; y-intercept is –20.
