To find the slope of a line that goes through given points with known coordinates, you divide the subtraction of the y of the second point minus the y of the first point, by the subtraction of the x of the second point minus the x of the first point:
m = (yB-yA) / (xB-xA)
Let A(8,5) and B(6,7).
With yB = 7; yA = 5; xB = 6; xA = 8
m = (7-5) / (6-8)
m = 2/-2
m = -1
So the slope of the line that goes through the given points (8,5) and (6,7) is m = -1.
I've added a pic of the line with both points under the answer.
Hope this Helps! :)
The value of the exponents in simple exponential form is 
.
The mathematical operation of exponentiation, written as bⁿ, involves the base number (b) and the exponent (or power) number (n). The way to say this word is "b (elevated) to the (power of) n."
- Exponentiation corresponds to repeated base multiplication when n is a positive integer since bⁿ is the outcome of multiplying n bases. The exponent is often displayed to the right of the base as a subscript.
- The phrase "b to the nth power" or simply "b to the nth" is used to refer to bn. Other variations are "b (raised) to the power of n," "the nth power of b," and "b to the power of n" and "b to the nth power,"
The properties of exponents tell us that when the bases are equal then on multiplication the powers are added and on division the powers are subtracted.

Answer: 9
Step-by-step explanation:
To calculate the sales tax that is included in a company's receipts from items subject to sales tax, divide the receipts by 1 + the sales tax rate. For example, if the sales tax rate is 6%, divide the total amount of receipts by 1.06. If the sales tax rate is 7.25%, divide the total receipts by 1.0725.

Hope this helped! Good luck!
Step-by-step explanation:
From the table we can make comparison between the distance travelled and the time taken. It can be seen that the time increases as the distance decrease.
If the car travels 700 miles in 0.5seconds and 600miles in 1.5secs, we can calculate the speed of the car using the formula;
v = change in distance/change in time
v = ΔS/Δt
v = 700-600/0.5-1.5
v = 100/-1
v = -100mi/hr
Since Speed = Distance/Time
-100 = 480/Time
Time = 480/-100
Time = -4.8s
Hence it will take the car 4.8seconds to travel 480miles.
