Find the slope intercept form for (2,4) (10,5)

Mathematics
1 answer:
adoni [48]3 years ago
8 0

As we move from the first point to the second, x increases from 2 to 10, so the change in x is 8.  At the same time, y increases by 1 from 4 to 5.  Thus, the slope is m = rise / run = 8/1 = 8.

Using the point-slope formula, we get y-4 = 8(x -2), or 8x - 16.

Isolate y.  To do this, add 4 to both sides, obtaining:

y = 8x - 12.  

This is the slope-intercept form for the equation of the line thru (2,4) and (10,5).

The price of a shirt has been discounted by $20. The sale price is $24.95. What percent of the original list price is the discou
Verizon [17]

Answer:

this is an example

Step-by-step explanation:

There are a few different ways to approach this problem, including the following two methods.

 

1) Find 20% of the original price, then subtract that amount from the original price. 

    To find a percentage of a number, you multiply the number by the percentage.  (You are finding a part of a whole.)

    

                   20% = 20/100 = 1/5    or   20% = 0.20

 

    Original Price: $24   Find 20% of $24.                         (Note: "of" is taking part of a whole, so you multiply.)

                

                    0.20 x 24 = 4.80            This is the mark down, or the amount you subtract from original price.

   

    Sale Price = Original Price - Mark Down   

                   =   24.00 - 4.80

                   =   19.20

 

2) If you save 20%, you are still paying 80%. (100-20 = 80) Therefore the sale price is 80% of the original price.

 

                    80% = 80/100 = 4/5     or    80% = 0.80

 

     Sale Price = 80% of Original Price

                    = 0.80 x 24

                    = 19.20
