Find the slope and y-intercept of the line.


How do I solve this.

Answers

Answer:

Slope:-63

Y-intercept: (0,825)

Step-by-step explanation:

Slope= y2-y1 ÷ x2-x1

321-699 ÷ 8-2

-378 ÷ 6 =-63

Y-intercept:  

y=-63x+b

to get b (y-intercept) plug in one of the points and solve.

​

699=-63(2)+b

699=-126+b

699+126=-126+126+b

699+126=0+b

825=b

A pair of sneakers are on sale for 20% off the original price. Tom purchased a pair of sneakers at this discounted price of $80. What is the original price of the sneakers?

write very professionally i need this for extra credit

Answers

The answer is 100.
You start by making a formula:
.80(x) = 80,
As we know the discount is 20% off, which makes the price actually 80% of what it originally was. Convert percent to a decimal gets you that .80
Reverse the process — 80/0.80 = 100
well the answer to your question is 100!

Simplify 3.1n - 1.1n

Answers

Answer:

2n

Step-by-step explanation:

The solution is, the value of subtraction is 2n.

What is Subtraction?

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers.

here, we have,

given expression is,

3.1n - 1.1n

we have to solve it, by subtraction.

now, we have,

3.1n - 1.1n

= (3.1 - 1.1 ) n

= 2 * n

=2n

at first, we take n common from both terms, then subtract 3.1 from 1.1, which is 2, then multiply the result 2 with n, finally we get the answer as 2n.

Hence, The solution is, the value of subtraction is 2n.
