Answer:
Line JK passes through points J(-4,-5) and K(-6, 3).
Line JK has form of y = mx + b
=> -5 = -4m + b
=> 3 = -6m + b
Subtract 2nd equation from 1st equation:
=> -8 = 2m
=> m = -4
Substitute back m = -4 into 1st equation:
=> -5 = -4(-4) + b
=> b = -21
Hope this helps!

Answer:
- a + 3b
Step-by-step explanation:
1*(2a-3b) + a
multiply 1*(2a - 3b) =(2a - 3b)
= - (2a - 3b) + a
-(2a - 3b) = -2a + 3b
-2a + 3b + a
simplify
-2a + 3b + a = - a + 3b
