Which graph represents a negative linear association between x and y? graph a graph b graph c graph d

First, only graph's a and b are linear, meaning the change in each step is the same. This eliminates graphs c and d, which are both exponential.
Next, we need to determine which graph is a negative relationship. In a negative relationship, small values of x mean large values of y and large values of x mean small values of y; this also means the slope is negative. This means graph b has all the properties we're searching for.

B

Step-by-step explanation:

From the graph the roots are x = 1 and x = 3, hence

(x - 1) and (x - 3) are the factors of the polynomial and the polynomial is the product of the factors, that is

y = a(x - 1)(x - 3) ← a is a multiplier , here a = 1, thus

y = (x - 1)(x - 3) → B
