The answer is -3
If you really think hard the slope will end up being -5/2 so it is -3

Answer:

-3

Explanation:

The slope formula is y2-y1/x2-x1, so replace the variables with the given values.

-5-5/1-x= -5/2, now multiply both sides by "1-x"

-5-5= -5/2(1-x) or -10=-5/2+5/2x, now add 5/2 to both sides

-20/2+5/2=5/2x, now simplify the equation

-15/2=5/2x, multiply both sides by 2/5

-30/10=x or x is -3
