Question

Need help solving this problem...

Answer 1

your answer is right...
when x=0, y=-6
the second difference of the y are same which indicates that it is a quadratic function..

Answer 2

It's linear , check all the values

Answer 3

linear
y=-3x-6

Answer 4

it only works with the first , it's not quadratic , it's linear

Answer 5

oh right, sorry:/

Answer 6

how do you solve this though, what are the steps?

Answer 7

what u need to do is substitute x values in the equations and see if u get the right y value

Answer 8

I think @aBaDy94 is giving an extensive explanation so I won't interfere

Answer 9

y=mx+y(When x=0)
m=(y2-y1)\(x2-x1)
m=(-9--6)\(1-0)
m=-3
y=-3x-6
