Answer:
y=x-2
Step-by-step explanation:
Slope intercept form is a way to describe a function using its slope and y-intercept and is written as y=mx+b.
m=slope
b=y-intercept
Looking at the graph we can see it goes through x=0 at y=-2 making -2 the y-intercept.
Then we must solve for slope, slope is rise/run. From the point (0,-2) the function travels to (7,0).
This gives us a rise (change in x) of 2 and a run (change in y) of 7 and 2/7 as our slope.
Answer:
$119520
Step-by-step explanation:
Given: Purchase price of Diamond ring= $12000
Value of ring increase by 32% each year.
First finding number of year between 2012 and 2040, to know the time period of value appreciation.
Time period=
∴ Time period of value appreciation is 28 years.
Now, finding the value of diamond ring increased after 28 years.
Value of ring increased after 28 years=
∴ Increased value of diamond ring after 28 years= $107520
Next, Value of diamond ring after 28 years=
Hence, value of diamond ring in 2040 is $119520
