Wanted, appreciated, and needed asaprelationship a has a lesser rate than relationship b. this table represents relationship b.

Let's assume

x is number of hours worked

y is amount paid

Since, this is linear relationship

We can select any two points

(2,36.50) and (4,73)

so, we can also write as

x1=2 , y1 =36.50

x2=4 , y2=73

Firstly, we can find slope

we can plug values

now, we can use point slope form of line

we can plug values

now, we can solve  for y

or

..............Answer

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
