You have to plug in a random y value and use algebra to solve for x. It is impossible to do without at least one point for y.
Answer:
Step-by-step explanation:
use equation to calculate the slope, in this case the slope would be
The slope would be 0 for the line,
another way we can tell the slope is 0 is that we can see the two sets of coordinates are on the y=11, they just have different x coordinates.
But the equation above shows the complete work and supported the answer.
Answer:
-12x = 60
Step-by-step explanation:
This is the type of problem that you just have to do a bunch of times until you get it right -- I don't think there's anything I can tell you that'll help you immediately. Ask for your teacher for more exercises of this sort or look it up online.
Good luck!
6 Books
$77.49 is the Total.
$3.99 is the Shipping.
$12.25 is the cost of each individual book.
First find the difference between the total and the shipping.
$77.49 - $3.99 = $73.50
Then divide the product with the cost of each book.
$73.50 ÷ $12.25 = 6 Books
