Answer:
(0, -4)
Step-by-step explanation:
I don't quite know how to explain it, but I was taught that the number in the equation that doesn't have a variable, in this case -4, is the y-intercept. The order pair is (0, -4) because a y-intercept is where the line crosses the y-axis and the y-axis is located on the 0 of the x-axis.
Answer:
Total number of copies sold till date are 381522.
Step-by-step explanation:
It is given in the question the book sold 35100 copies in its first month of release and this number is 9.2% of the number of copies sold till date.
To find is how many copies have been sold.
Let the total number of copies sold be = A
Therefore 9.2% × A = 35100
![\frac{9.2}{100}A=35100](https://tex.z-dn.net/?f=%5Cfrac%7B9.2%7D%7B100%7DA%3D35100)
![A=\frac{35100\times 100}{9.2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B35100%5Ctimes%20100%7D%7B9.2%7D)
A = 381521.74 ≅381522 copies
In order to find the equation of a line, you would have to use the equation y=mx+b.
First, find the slope:
![\frac{y_{2}- y_{1} }{x_{2} x_{1} }](https://tex.z-dn.net/?f=%20%5Cfrac%7By_%7B2%7D-%20y_%7B1%7D%20%7D%7Bx_%7B2%7D%20x_%7B1%7D%20%7D%20)
There is (1,8) and (2, 16) so plug that in 16-8/2-1 = 8. That's your slope! (Or the m)
Next in order to find b, you have to plug in a point:
y=8x+b
Take (1,8) and plug it in for x and y:
8=8(1)+b
b=0
Your y intercept is 0 (which you can also see on the graph)
So your answer is: y=8x
The answer will be definitely be A don’t listen
Distance = rate x time
Distance = 221 miles
Rate = 68 mph
221 miles = 68 mph x time
221 miles/68 mph = time
3.25 hours = time
