Answer:To determine the slope of a line that is parallel to the given line, we need to find the slope of the given line first.
To do this, we need to rewrite the equation in slope-intercept form, which is y = mx + b, where m represents the slope.
Let's rewrite the given equation -7x + y = 7 in slope-intercept form:
y = 7x + 7
From the equation, we can see that the slope of the given line is 7.
Since parallel lines have the same slope, any line that is parallel to the given line will also have a slope of 7.
