Plug them into point-slope form.
y - y1 = m(x - x1)
Where y1 is the y-value of the point, x1 is the x-value, and 'm' is the slope.
Plug in what we know:
y - 4 = -5(x + 2)
So one of our answers is C.
Now distribute -5 into the parenthesis:
y - 4 = -5x - 10
Add 4 to both sides:
y = -5x - 6
Add 5x to both sides:
5x + y = -6
So the other answer is B.
Answer:
10,000
Step-by-step explanation:
Given:
The graph of an exponential function.
To find:
The function in the form of
.
Solution:
The general form of an exponential function is
...(i)
From the given graph it is clear that the function passes through the points (0,4) and (1,7). It means these points will satisfy the function.
For x=0 and f(x)=4,



For x=1 and f(x)=7,

Putting a=4, we get


Substitute a=4 and
in (i).

Therefore, the required exponential function is
.
