Graph the line. x+y=4

So I need to graph this. So as not to feel guilty about just taking the answer..well lets say cheatingyeah I said it (Cringe) I dont like that. but whatever I tired solving it myself.

so here is what I did.

So I think I have to substitute x and y with any variable. So this is what I got...

2+2=4

so is the point (2,2)?

I think it's a whole line so there has to be more than one point.

and you're right are the (2,2)

but there should also be (1,3) (3,1) and (4,0)

and you can keep going as long as it equals 4

like (-1,5)

after you plot the points join them up to form a line

after simplifying it i got: -36.25 as my answer. hope that !

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
