Step-by-step explanation:
represent price per video game.
represent demand.
The linear equation in slope intercept form can be represented as:

where
is slope of line or rate of change of demand of game per dollar change in price and
is the y-intercept or initial price of game.
We can construct two points using the data given.
When price was $66 each demand was 400. 
When price was $36 each demand was 1300. 
Using the points we can find slope
of line.




Using point slope form of linear equation to write the equation using a given point.

Using point
.

⇒
[Using distribution]
Adding 400 to both sides:
⇒ 
⇒
The linear relationship between price and demand can be written as:

Answer:
45
Step-by-step explanation:
To find the area of any right triangle, meaning a triangle with a right angle, you use 1/2 base x height
So... here the base is 9 and the height is 10
Therefore: 1/2 x (9) x (10)
1/2 x 90
= 45
Answer:
45 / 56
