Step-by-step explanation:
Given equation:

For two lines to be parallel, the slope of one will be the same as the slope of the second line

comparing the given equation with the equation of line:

This means the slope of the 1st line is -1. The slope of the second line will also be -1 since they are parallel
To get the y-intercept of the second line, we would insert the slope and the point given:
point given: (-7, 3) = (x, y)

The second equation is the equation of line that is parallel to the line y = -x + 1 and passes through (-7, 3)
Second equation:
