Answer:
1924.3
Step-by-step explanation:
Ok
You need to write an expression for the change in value
the change is linear, so you will get a line equation y = mx + b
y-axys : value
x-axys : years
New Hampshire:
Slope =
the y-intercept will be 37600 because you can assume that 1950 = 0, and 2000 = 50
y = 1914*x + 37600
Massachussets:
Slope =
Same as above, the y-intercept is 55400
y = 2606*x + 55400
Now you need to equal the value for both and find the year "x"
1914x + 37600 = 2606x + 55400
- 692x = 17800
x = -25.7
Since i considered x = 0 to be 1950; the actual year is 1950 - 25.7 = 1924.3
