How many points are needed to name a specific line?

Answers

Two.

Example: a•------------------•b

You can't just call the line Line A because A is not a line, it's a point. But if you add another point, it makes a line, which would be called Line AB.

What is the slope of a line through (-5, -10) and (-1, 5)

Answers

Answer:

m = 15/4

Step-by-step explanation:

slope (m) = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (-5 , -10)

(x₂ , y₂) = (-1 , 5)

Plug in the corresponding numbers to the corresponding variables:

m = (5 - (-10))/(-1 - (-5))

m = (5 + 10)/(-1 + 5)

m = (15)/(4)

m = 15/4 is your answer.

A movie theater charges 5 for an adult ticket and 2 for a child's ticket. One Saturday the theater sold 785 tickets for 3,280. How many adult and children tickets were sold for the movie saturday?

Answers

Answer: 570 adult tickets and 215 children tickets were sold

Step-by-step explanation:

Let x represent the number of adult tickets that were sold for the movie Saturday.

Let y represent the number of children tickets that were sold for the movie Saturday.

One Saturday the theater sold 785 tickets. This means that

x + y = 785

The movie theater charges 5 for an adult ticket and 2 for a child's ticket. The total sales on Saturday was 3280. This means that

5x + 2y = 3280 - - - - - - - - - - --- 1

Substituting x = 785 - y into equation 1, it becomes

5(785 - y) + 2y = 3280

3925 - 5y + 2y = 3280

- 5y + 2y = 3280 - 3925

- 3y = - 645

y = - 645/- 3

y = 215

x = 785 - y = 785 - 215

x = 570
