Answer:
-5/-2 or 2.5
Step-by-step explanation:
Because you gave two points that I'm guessing are from the graph I think that's the answer. Because when you use the slope formula y2-y1 over x2 - x1 you get -5/-2 or you either get 2.5 meaning that is the slope specifically saying the rate of change. You get 2.5 when you divide -5/-2 incase you need a decimal or want to simplfy it.

Answer:
C
Step-by-step explanation:
∆=b^2-4a*c=1-4*3*(-10)=121>0 có 2x
x1=-b+sprt∆/2a=1+sprt121/2*3=2
x2=-b-sprt∆/2a=1-sprt121/2*3=-5/3
The two points are exactly eight units apart.
The equation for this line is...
y = -x
Or
x + y = 0
