What is the slope of the line which passes through (−2, 0) and (0, 4)?

avanturin [10]

Answer:

slope = 2

Step-by-step explanation:

Slope of a line given two points can be found using slope formula:

$\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}$

Given two points (-2, 0) and (0, 4):

$x_{1}=-2 \\x_{2}=0\\y_{1}=0\\y_{2}=4$

Plug them into the equation:

$\frac{(4-0)}{(0--2)}=\frac{4}{2}=2$

Ravi ordered some books online and spent a total of $89. Each book cost $5 and he paid a total of $4 for shipping. How many book

Katyanochek1 [597]

Answer:

He bought 17 books.

Step-by-step explanation:

Given that:

Total money spent = $89

Cost of each book = $5

Shipping price = $4

We have to find, Total number of books

So if the number of books be represented by b, the equation will become:

Cost of one book * total number of books + shipping price = total money

Putting values we get:

5*b + 4 = $89

By simplifying:

5*b = 89 - 4

5*b = 85

Dividing both sides by 5 we get:

b = 17

So the total number of books bought is 17.

i hope it will help you!
