What is the slope of the line that passes through the points (5,-4) and (7,-4).

the slope is 0

Step-by-step explanation:

the slope is zero because to find the slope the equation is the second y - the first y over the second x - the first x to it would be -4 - -4 which is 0 over 7-5 which is 2 so it would be 0/2 and that is 0. You can also tell because if you mark them down on a graph, the line would be completely horizontal with a slope of 0

step-by-step explanation:

i think you should think about the question and not look online.

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.
