Answer:
-28
Step-by-step explanation:
The big thing to remember here is
Slope=Rise/Run
We can put x for the run and get this equation
21/x=-3/4
From here it gets really easy. To find the value of x we can change -3/4 into 21/-28 because in this case we need a common numerator. 21/x=21/-28 and it is obvious that x=-28
Hope this helped let me know if you have questions.
