Ms. Chang has 24 students in her class, and 8 of them are boys. Let's find out the ratio of girls to boys.
=> g : b
=> (24-8) : 8
=> 16 :8
=> 16 / 8 = 2
=> 2 : 1 is the ratio of girls to boys.
Of course! so basically for each value of x, for example -6, plug it into the equation. so for -6 do -2/3(-6)+7. hope this helps!
ASSUMPTION: Since we are talking about fractions it looks like you have to simplify it. Again, its still a guess so Id assume..
16/12 = 4/3.. So It should be <em>h = 2 </em>
