If my explanation doesn't make sense, there are some pretty good utube videos about it.
Here is our equation: 3x + 2y = 5
At the y-intercept (the point where the line meets y on a graph), x=0. The same can be applied to the x-intercept, as y=0. So, to find each intercept, we can treat 3x + 2y = 5, as we would with any other equation.
First, we will find the y-intercept. We know x=0, so that can be plugged in: 3(0) + 2y = 5
Anything times 0 is 0.
2y = 5
Divide both sides by 2 to isolate y:
y = 5/2 (or 2.5)
The y intercept is 5/2 (or 2.5).
Now, do the same for x, given that y=0: 3x + 2(0) = 5
Anything times 0 is 0.
3x = 5
Divide both sides by 3 to isolate x:
x = 5/3 (or 1.7
The x intercepts is 5/3 (or 1.7)
(You should probably use the fractional versions of the answers, but it depends on your teacher, I suppose)

X = 9
y = 6
Step by step:
Divide 15 by 2: 15 ÷ 2 = 7.5
Subtract 0.5 from 7.5 (this will later be added back): 7.5 - 0.5 = 7
Subtract 1 from 7 (she wants to buy at least 2 more children books): 7 - 1 = 6
Subtract 6 from 15 (6 being the number of puzzle books, 15 being the total number of items): 15 - 6 = 9 (number of children books)
Answer:
Graph C shows the line of best fit for the data.
Step-by-step explanation:
The line of Graph C is more centered and even than the other ones
