Answer: 9/2
Step-by-step explanation:
To find the slope of a line, you must use the equation y2-y1/x2-x1.
The first part (the y1 and the x1) will be the points (2,5) and your second part (the y2 and the x2) will be (0,-4)
Plug them in like this (5+4)/(2-0) (Note that the negative four becomes a positive due to the negative sign that was already in place in the equation.)
Then you add them together giving you 9/2.
