Answer:
Step-by-step explanation:
A. Directrix: y = 4-6 = -2
:::::
B. Axis of symmetry: x = 6
Axis of symmetry intersects directrix at (6,-2)
:::::
C . Vertex is halfway between focus and directrix, at (6,1)
:::::
D. The focus lies above the directrix, so the parabola opens upwards.
:::::
E. Focal length p = 1/(4×0.5)
:::::
F. p = 0.5
::::
G. y = 0.5(x-6)² + 1

Rise over run is 7 over 2 so 7/2 is the slope
Regular is
$97.99 after sale price is 83.30
97.99- 83.30= 14.69 is the discount
You can do it same way with B C and D
Answer: 1/3
Step-by-step explanation:
- Two points on this graph are (40, 80) and (70, 90). These points can be used to find the slope.
- The formula for slope is (y2-y1)/(x2-x1).
- Plugging our numbers into the formula:
- (80-90)/(40-70) = (-10)/(-30) = 1/3
