In which quadrant does θ lie given that sinθ > 0 and cos θ < 0

Lindsay used two points, (x,y; ) and (+2.82), to find the equation of the line, y = mx + b, that passes through the points. y2-y, first, she used the definition of slope and determined that the value of mis x, - . given this information, which expression must represent the value of b?

Which of the following is the true for f(x) = 5cos

(60 points) explain this in detail
