Answer:
The most straightforward way to obtain the expression for cos(2x) is by using the "cosine of the sum" formula: cos(x + y) = cosx*cosy - sinx*siny. cos(2x) = cos² (x) - (1 - cos²(x)) = 2cos²(x) - 1. = 2cos²(x) - 1.
Step-by-step explanation:
Y = -4/5 + 7, the 7 is the slope intercept and the -4/5 is the slope

= 3 - 2 + 8
= 11 - 2
= 9
In short, Your Answer would be Option B
