PLEASE HELP! I’m struggling with each part any help will be amazing

Answer:

<u>slope:</u> -5/2

<u>y-intercept</u>: (0, 2)

<u>Linear function</u>: y = -5/2x + 2

Step-by-step explanation:

Given points (-2, 7) and (2, -3):

Use these points to solve for the slope of the line using the formula:

m = (y2 - y1)/(x2 - x1)

Let  (x1, y1) =  (-2, 7)

      (x2, y2) =  (2, -3)

Substitute these values into the equation:

m = (y2 - y1)/(x2 - x1)

m = (-3 - 7) / [2 - (-2)]

m = -10/ (2 + 2)

m = -10/4 = -5/2

Therefore, the  slope of the line in reduced form is m = -5/2.

The y-intercept is the <u>y-coordinate</u> of the point (0, <em>b</em>) where the graph of the linear equation crosses the y-axis of the Cartesian grid. The y-intercept is also the value of y when x = 0.

To solve for the y-intercept, use one of the given points (2, -3) and the slope (m = -5/2), and substitute their values into the slope-intercept form:

y = mx + b

-3 = -5/2(2) + b

-3 = -5 + b

Add 5 to both sides to solve for the y-intercept, b:

-3 + 5 = -5 + 5 + b

2 = b

Given the value of b = 2, it means that the y-intercept is (0, 2).

Therefore, given the slope of -5/2, and the y-intercept, b = 2:

The linear equation in slope-intercept form is: y = -5/2x + 2

If each can costs $23.97 plus 6% tax, what is the total cost? Round to two decimal places.
kap26 [50]
The total cost for one can is: $25.41.
__________________________________________________
Let us assume that we want to know the total cost of ONE CAN.
_____________________________________________
To calculate our answer:
_______________________________
$ 23.97 + [ (6/100) * 23.97)] = Our answer, in dollars.
__________________________________________
Note: "6%" = 6/100 = 0.06
_______________________
Rewrite as:
____________
$ 23.97 + [ (6/100) * 23.97)]  = our answer, in dollars; 
_____________________________________________
    $ 23.97 + (0.06 * 23.97)

            =    $ 23.97 + 1.4382

            =      $ 25.4082 ; Round to decimal places, to get:
                                         <span>→ $ 25.41
