Answer:
d. -7/25
Step-by-step explanation:
π<θ<3π/2 in third quadrant
tanθ = 4/3
sinθ = - 4/5
cosθ = - 3/5
cos 2θ = cos²θ - sin²θ = (- 3/5)² - (- 4/5)² = 9/25 - 16/25 = - 7/25
Answer:
y = -2x + 3
Step-by-step explanation:
If you use the formula to find slope, which is y2-y1 over x2-x1, you can find the slope is -2. the only equation that has -2 as the slope is the first one, y = -2x + 3. hope I helped!
