Final answer:

To find the equation of a line parallel to the line 2x + 5y - 15 and passing through the point (-10, 1), determine the slope of the given line and use it to write the equation.

Step-by-step explanation:

To find the equation of a line that is parallel to the line 2x + 5y - 15 and passes through the point (-10, 1), we need to find the slope of the given line and use it to write the equation.

  1. First, let's rearrange the equation of the given line to slope-intercept form (y = mx + b) by isolating y.
  2. 2x + 5y - 15 = 0 becomes 5y = -2x + 15, then y = (-2/5)x + 3.
  3. The slope of the given line is -2/5, so the slope of any line parallel to it will also be -2/5.
  4. Now, we can use the point (-10, 1) and the slope (-2/5) to write the equation of the parallel line using the point-slope form (y - y1 = m(x - x1)).
  5. Plugging in the values, we get y - 1 = (-2/5)(x + 10).
  6. Simplifying the equation, we have y - 1 = (-2/5)x - 4.
  7. Finally, rearranging the equation gives us the equation of the line parallel to the given line and passing through the point (-10, 1): y = (-2/5)x - 3.
