Answer this and explain = Medal and fan!!!!!
Use the function rule to complete the table:
-10x + y = 4
x= -2, -1, 0, 1, 2
y=

you have to plug in the numbers that x equals first. one at a time. -10*-2 +y-=4
OpenStudy (anonymous):
Ok, Im getting it, but explain a bit more
OpenStudy (anonymous):
that would give you 20+y=4
OpenStudy (anonymous):
then you subtract 20 to both sides and you end up with y=-16

So I multiply -10 x -2
Or 10 x -2?
OpenStudy (anonymous):
you multiply -10*-2
OpenStudy (anonymous):
Which gives me 20 right?
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
And then?

you subtract 20 from 20 which gives you 0 leaving the y by itself and then you subtract 4-20 which gives you -16
OpenStudy (anonymous):
Why do i have to subtract? Is it a rule, that I have to subtract from both sides? I do that every time?
OpenStudy (anonymous):
Well, thanks. i get it more now ;)
OpenStudy (anonymous):
you have to subtract to get y by itself

Ok
OpenStudy (anonymous):
now if you plug it in it should give you 4. with all the equations if you do it right. -10*-2+(-16)=4
OpenStudy (anonymous):
your welcome

Thanks
