Answer:
-4/3
Step-by-step explanation:
- since the both lines are perpendicular the product of their slopes equals -1
- let m be the slope of the red line
- m*a = -1
- m = -1/a
- a = (8-5)/(0-(-4)) = 3/4
- so m = -4/3
Did you mean -10? If so that is -1 and 10. 10 and 9 is not possible to answer.
-1+10=9
-1*10=-10
