The formula for slope is y = mx + b
y is the y value, m is the slope, x is the x value, and b is the y intercept.
The equation given for line e is
[tex]y = \frac{ - 9}{2} x + 7[/tex]
Therefore the slope of line e is -9/2
Line f is parallel and parallel lines have the same slope.
So the slope is line f is -9/2.
The picture isn't that clear and I can't really tell if it's-9/2 or 9/2.
But whatever it is, the slope of line f is the same as the slope of line e because they are parallel.
Good luck!
