HELP WANTED, APPRECIATED, AND NEEDED ASAP
Anit [1.1K]

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

m=\frac{y_2-y_1}{x_2-x_1}

we can plug values

m=\frac{73-36.50}{4-2}

m=18.25

now, we can use point slope form of line

y-y_1=m(x-x_1)

we can plug values

y-36.50=18.25(x-2)

now, we can solve  for y

y=18.25x

or

y=18.3x..............Answer
