She had this totally wrong (no offence Julia).
She had no right to be able to put [tex]\boxed{3x+2}[/tex], and based on this, this was the start of her not able to properly finishing this answer. I'm not sure if I were to do this a different method, but I got a totally different answer.
The way the I would conclude with this problem would be the following:
[tex] 4*x+5*y-(48)=0 \\ \\ we \ would \ have \ an \ example \ of \ an \ equation \\ such \ as \ the \ following... \\ \\ Such \ an \ equation \ is \ usually \ written \\ (y=mx+b ("y=mx+c")[/tex]
Therefore, as your correct answer, [tex](x) \ and \ (y)[/tex] would then equal the following:
[tex] x-intercept = 48/4 \Longleftarrow \\ \Longrightarrow
\ \ ; y-intercept = 48/5 [/tex]
