Encontrar funciones trigonométricas en un triángulo rectángulo

What is the point-slope form of theequation for the line with a slope of-2 that passes through (1, 4)? a y + 1 = -2(x + 4)b y-1=-2(x-4)c y + 4 = -2(x + 1)d y - 4 = -2(x - 1)

Find the number of real number solutions for the equation. x2 + 5x + 7 = 0 0 cannot be determined 1 2

Asequence is defined recursively using the formula f(n + 1) =f(n) - 5. which sequence could be
