You're meant to make one side of the equation equal 0.
For example, the first problem is

+ 9k = -7
You'd add 7 to both sides, leaving you with

+ 9k +7 =0
And I assume you know how to factor??
The order of these numbers from smallest to largest is:
(-1)2, -1 2/5, -1.4, (1/2)2
-1 2/5 and -1.4 are technically the same, though.
Complete Question
The relationship between altitude and the boiling point is linear. At an altitude of 8300ft, the liquid boils at 194.23 ° F
At an altitude of 4200 ft , the liquid boils at 202.02° F.
Write an equation giving the boiling point b of the liquid, in terms of altitude a in feet . feet . What is the boiling point of the liquid at 2600ft
Answer:
The equation is 
At 2600ft the temperature is 
Step-by-step explanation:
From the question we are told that
The temperature at 8300ft is 194.23 ° F
The temperature at 4200 ft is 202.02° F
Generally the slope for this relationship is mathematically represented as

=>
Generally the according to the point slope formula is

=> 
=> 
=> 
Now we are given from the question that x = 2600 ft
Then

=> 
Answer:
So what we need to do to write the equation is to know our slope or rate of change and to know our initial value or where the line is touching the y axis the y intercept.
