Final answer:

The equation of a line parallel to y = 2/3x – 7 and passing through the point (-3, 1) is y = 2/3x + 3. This is found by using the point-slope form with the given point and the slope of the original line.

Step-by-step explanation:

To write the equation of a line that is parallel to a given line and passes through a specific point, you must follow these steps:

  • Identify the slope of the given line.
  • Use the same slope for the new line, since parallel lines have equal slopes.
  • Apply the point-slope form with the given point and the slope.

In this case, the given line is y = 2/3x – 7. The slope (m) of this line is 2/3.

The point given is (-3, 1). Using the point-slope form, which is y - y1 = m(x - x1), where (x1, y1) is the given point, we can substitute m = 2/3 and (x1, y1) = (-3, 1):

y - 1 = 2/3(x + 3).

To find the y-intercept, expand and simplify this equation:

y - 1 = 2/3x + 2

y = 2/3x + 3

This is the equation of the line that is parallel to y = 2/3x – 7 and passes through the point (-3, 1).
