When a line is translated, its slope remains unchanged. Only the position of the line on the coordinate plane changes.
In this case, the original line has the equation \( y = 7x - 3 \), which has a slope of 7. After translating the line 5 units to the left and 2 units up, the new line will also have a slope of 7.
So the correct statement is:
The slope of the translated line remains 7.
