Answer:
The amount of jobs from fitting industry shall decline in 5.5 percent from 2015 to 2025.
Step-by-step explanation:
Due to the assumption of a yearly average rate, a linear function model shall be used. The expected amount of jobs (
) after a certain amount of years (t) is given by the following formula:
Where:
- Initial amount of jobs in pipe fitting industry, measured in thousands.
- Average yearly rate, measured in thousands per year. (A decline is indicated by a negative sign)
If 
, 
and 
, then:
The percent change in jobs from pipe fitting industry is calculated as follows:
The amount of jobs from fitting industry shall decline in 5.5 percent from 2015 to 2025.
1: Assuming this line is linear, the first thing to do is find the slope.
The slope formula is
, so in this case, it is
, which comes to
. Then, use your slope and one of the points given to write the point-slope formula of the linear equation, and then written in standard form:
y=
x-
.
2. Use the same process as in question 1 to find:
y=-7x+11
Answer:
If you compute the slope between any two points that must be the same, that's how you can tell if a table represents a linear function.
Remember that the slope between any two points (x1,y1), (x2,y2) is
slope = ( y2 - y1 ) / (x2 - x1)
Step-by-step explanation:

slope = ( y2 - y1 ) / (x2 - x1)
Answer:
-22
Step-by-step explanation:
-14+(-12）+4
=-14-12+4
=-26+4
=-22
