Which of the following is the equation that represents the graph?

Graph of a line the passes through the points negative 6 comma 0 and 0 comma negative 4.
y equals negative two thirds times x minus 6
y equals negative three halves times x minus 6
y equals negative two thirds times x minus 4
y equals negative three halves times x minus 4

1 answer

To determine the equation of the line that passes through the points (-6, 0) and (0, -4), we first need to find the slope of the line.

The formula for the slope \( m \) between two points \((x_1, y_1)\) and \((x_2, y_2)\) is:

\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]

Substituting the points \((-6, 0)\) and \((0, -4)\):

\[ m = \frac{-4 - 0}{0 - (-6)} = \frac{-4}{0 + 6} = \frac{-4}{6} = -\frac{2}{3} \]

Now that we have the slope \( m = -\frac{2}{3} \), we can use the point-slope form of the line equation:

\[ y - y_1 = m(x - x_1) \]

We can choose one of the two points; let's use the point (0, -4):

\[ y - (-4) = -\frac{2}{3}(x - 0) \]

This simplifies to:

\[ y + 4 = -\frac{2}{3}x \]

Subtracting 4 from both sides gives:

\[ y = -\frac{2}{3}x - 4 \]

Thus, the correct equation of the line is:

\[ y = -\frac{2}{3}x - 4 \]

Now, let's match this with the options given:

  1. \(y = -\frac{2}{3}(x - 6)\) -- This would not correctly represent the line.
  2. \(y = -\frac{3}{2}(x - 6)\) -- This has the wrong slope.
  3. \(y = -\frac{2}{3}(x - 4)\) -- This represents a different line.
  4. \(y = -\frac{3}{2}(x - 4)\) -- This also has the wrong slope.

None of the provided options correctly represent the equation derived.

If you would like to use either point in the point-slope form again or check the options in different terms, or if you can provide more details about the adaptation of these options, I can help further.
