A. The answer is 2. It does not matter what x is.
21 over 50 is
21/50.
The same thing, just put 21 on top, a line under it, and below that line, put the 50
So for this function we will be using the quadratic formula, which is 
, to solve. a = x^2 coefficient, b = x coefficient, and c = constant. Using our equation, we can solve for the zeros (x-intercepts) as such:
In short, your x-intercepts (rounded to the hundredths) are (1.92,0) and (-3.92,0).

Answer:
y = -3/2x + 1 1/2
Step-by-step explanation:
the slope would be -3/2 because you have to find the reciprocal and switch the sign. To find the y intercept you would plug in the points to the equation.
6 = -3/2(-3) + b
6 = 4.5 + b
1.5 = b
