Question

X-9y=12 what makes this equation true
(12,0)
(0,12)
(3,-1)
(0,-4/3)

Answer 1

you have to input each solution into the equation.
let’s start of with (12,0)
12-9(0)=12
12=12 <— which is true so it’s this one
let’s do the other ones to check

now let’s do (0,12)
0-9(12)=12
-108=12 <— not true

(3,-1)
3-9(-1)=12
13=12 <— not true

(0,-4/3)
0-9(-4/3)= 12
12=12 <— also true

the answer would be (12,0) and (0,-4/3). i’m not sure whether or not it’s a select all that apply question. i hope this helps
