What is an equation of the line that passes through th (3,-1) and has a slope of 2?

1 answer:

4 0

The given point to us is (3,-1) and the slope of the line is 2 . We can use the point slope form of the line as ,

$\sf\longrightarrow m ( x - x_1) = y - y_1$

Substitute the values ,

$\sf\longrightarrow 2( x - 3 ) = y - (-1)$

Simplify LHS and RHS ,

$\sf\longrightarrow 2x - 6 = y +1$

Put all terms on one side ,

$\sf\longrightarrow \boxed{\bf 2x - y -7=0}$

how many wall are there in your room? what are the shape of the floor and ceiling in your room ? how can you find the area of ea

Triss [41]

My room is made up of four walls, both the floor and the ceiling are rectangular in shape.

There are four walls in my room.
The shape of the floor is a rectangle and given that the ceiling is the same form above the floor, it is also shaped as a rectangle.

To get the area of a rectangle, you use this formula since my floor and ceiling are rectangle.

Area = L * W

where

L = length

W= width

But if you have a square floor and ceiling, the area of a square is

Area = s²

given that it is side * side.

In conclusion, there are 4 walls in every room. The shape of the ceiling or floor could be a rectangle or a square. It depends on your room and its measurements. To get the area, multiply the length by the width.
