A function of x containing three ordered pairs of the form (x,y) is shown below

A)The slope of function is 15

B)  Point slope form :

Slope-intercept form : y=15x+325

Standard form: 15x+y=325

C)g(x)=15x+325

D) The balance in the bank account after 12 days is $505  

Step-by-step explanation:

x                     g(x)

0                    $325

5                    $400

10                  $475

Part A: Find and interpret the slope of the function.

Formula of slope =

We are given that

Substitute the values in the formula:

m=15

So, The slope of function is 15

Part B: Write the equation of the line in point-slope, slope-intercept, and standard forms.

Point slope form :

Slope-intercept form =

Standard form :

So,

Part C: Write the equation of the line using function notation.

Part D:  What is the balance in the bank account after 12 days?

Substitute x = 12

So,

Hence the balance in the bank account after 12 days is $505
