y= 1/-2x + b

The standard slope intercept form would be y =mx+b

"m" would be the increase/decrease or what makes the line go up or down,

and the "b" would be the height in which it starts at

Hope this helped.

y=12x+120

y=12(26)+120

y=312+120

y=432 (No)

B.)34

y=12x+120

y=12(34)+120

y=408+120

y=528 (No)

C.)44

y=12(44)+120

y=528+120

y=648 (No)

D.)24

y=12x+120

y=12(24)+120

y=288+120

y=408 (Yes)

The other way is setting it equal to...

12x+120=408

Isolate the variable...

12x+120=408
-120 -120

12x=288

x=24
Thus (D) is you answer!

Hope this helps!
