You didnt list any graph?? Can you add it please :)
Here's the answer, using the quadratic formula
There are 39 boys.
First you divide 4 into 52 because there are 3 boys for 4 girls.
Then you take the quotient, 13, and multiply by 3.
T he x and y intercepts of the equation:
are : y-intercept is (0,-5) and x-intercept is (4,0)
So, Option D is correct.
Step-by-step explanation:
we need to identify the x and y intercepts of the equation: 
Finding x-intercept
For finding x-intercept put y=0
We are given the equation:

Solving:

So, x-intercept is (4,0)
Finding y-intercept
For finding y-intercept put x=0
We are given the equation:

Solving:

So, y-intercept is (0,-5)
the x and y intercepts of the equation:
are :y-intercept is (0,-5) and x-intercept is (4,0)
So, Option D is correct.
