Answer:
Step-by-step explanation:
Slope-intercept equation of a line is,
y = mx + b
Here, m = Slope of the line
b = y-intercept
If m = -6 and b = 3,
Equation of the line will be,
y = -6x + 3
Input - output values got the graph of this line,
x -1 0 1 2
y 9 3 -3 -9
Now by plotting these points we can draw the line on graph.
Answer: (B) 3 times as fast
<u>Step-by-step explanation:</u>
rate of change is the "slope" between the given interval.
f(x) = 125(.9)ˣ
f(1) = 125(.9)¹
= 112.5
f(5) = 125(.9)⁵
= 73.8
********************
f(11) = 125(.9)¹¹
= 39.2
f(15) = 125(.9)¹⁵
= 25.7
********************
The rate of change from years 1 to 5 is approximately 3 times the rate of change from years 11 to 15.
