False they don't have to be whole numbers. As long as they're greater than 0
X intercepts are 2 and -1/2
20 % of the price: 0.2 · 840 = $168
The rest: $840 - $168 = $672
$372 : 6 = $112
The amount of each monthly payment will be $112.
Since it is in absolute value it switches the negative to a positive so here let me show you
|6+y| = 2
If you try -4 you get 2 in a positive form so -4 is one correct.
The second correct one is -8 because 6-8 is -2 but as I was saying before how the absolute value changes it into positive, that means -2 would be switched to 2 meaning that -8 is also a correct answer.
If you need more help just search up what absolute value is.
