Write an equation in point-slope form for the line through the given point with the given slope.

(–3, –7); m = -6/5

1 answer

To write the equation of a line in point-slope form, you use the formula:

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

where \((x_1, y_1)\) is a point on the line and \(m\) is the slope. In this case, the point is \((-3, -7)\) and the slope \(m = -\frac{6}{5}\).

Plugging in the values:

  • \(x_1 = -3\)
  • \(y_1 = -7\)
  • \(m = -\frac{6}{5}\)

The equation becomes:

\[ y - (-7) = -\frac{6}{5}(x - (-3)) \]

This simplifies to:

\[ y + 7 = -\frac{6}{5}(x + 3) \]

So the equation of the line in point-slope form is:

\[ y + 7 = -\frac{6}{5}(x + 3) \]
