Answer:
(A)A coordinate plane with a line starting at (negative 2, negative 4), passing through (0, negative 2) and (2, 1).
Step-by-step explanation:
Given the line: y=x-2
Comparing with the slope-intercept form y=mx+b
- Slope, m=1
- y-intercept is -2.
Therefore, the point (0,-2) must be on the line.
Only Options A and D have this point.
We then determine which has a slope, m=1.
<u>Option A</u>
Using points (-2,-4) and (0,-2)
Slope,
<u>Option D</u>
Using points (-3,0) and (0,-2)
Slope,
Therefore, Option A satisfy the requirements.
Answer:
The correct option is 2.
Step-by-step explanation:
It is given that Jane bought a car for $30,303. The value of the car depreciated at a constant rate per year.
The exponential growth and decay function is defined as
Where, P₀ is initial value and r is growth rate.
The initial value of car is $30,303. Let the rate of depreciation be x%.
It means rate of depreciation is 15%. Since the value of car decreased by 15% per year, therefore growth rate is -0.15.
Therefore option 2 is correct.
