Find the slope of the line from the graph
Someone please help and explain!!

slope = -5/2

Step-by-step explanation:

The slope is also commonly referred to as the rate of change.  The slope is a single number that allows us to determine the direction in which a line is slanting from left to right, as well as how much slant there is to the line.

To find out what the slope is, we can select two points from the graph and use the following formula:

The two points that I've selected are: (1, 5) and (3, 0).

Let x1 = 1

x2 = 3

y1 = 5

and y2 = 0.

Plug in those values into the slope equation:

Therefore, the slope of the graph is -5/2.  It is a negative slope because it is sloping down from left to right.

The slope of  -5/2 represents the downward vertical change in y (rise) over the horizontal change in x (run).

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
