Find the reference angle for -369°

351°

Step-by-step explanation:

-369° + 360° = -9°.  This is in Quadrant IV.  If you want a reference angle in Quadrant I, find the positive angle between 0 and 360° that has the same terminal point at does -9°.  It is 360° - 9° = 351°

the answer is 13/48

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
