Answer: A
Step-by-step explanation: put it into point slope-form
y-ysub1=m(x-xsub1)
m=slope=(-2-3)/(2-(-1))=-5/3
ysub1 is 3 and xsub1 is -1
so substitute: y-3=-5/3(x-(-1))
y-3=-5/2(x+1)
Assuming the 2nd one is 4a^2 - 20a +25, it is the one you're looking for. It factors to be (2a-5)^2
-12n/35-13n/35
= (-12n-13n)/35
= -25n/35
= - 5n/7
