Parallel line means they have the same slope
y = mx + b
where m = slope
y = -3 + 4
here the slope is negative 3
y = -3x + b
plug in (4, 8)
8 = -3(4) + b
b = 8 + 12
b = 20
The answer is y = -3x + 20
Answer: 
<u>Step-by-step explanation:</u>
P(x) = x⁴ - 3x² + 4x + 5
g(x) = x² + 5
<u>_x²_- 8 </u>
x² + 5) x⁴ + 0x³ - 3x² + 4x + 5
-<u>(x⁴ + 0x³ + 5x²) </u> ↓ ↓
-8x² + 4x + 5
-<u>(-8x² + 0x - 40)</u>
4x + 45

just listen to ur teacher and u will learn something LOL
For the equation,
y = 1/2(x+3)^2 -5
The vertice is (-3,-5). Therefore the axis of symmetry is X = -3.
