Point slope form of (2,4) and (3,1)

y-4 = 3 (x-2)

Step-by-step explanation:

To find the slope of a line

slope = (y2-y1)/(x2-x1)

slope = (1-4)/(2-3)

         = -3/-1

         =3

Now we use the point slope form for a line

y-y1 = m(x-x1)

y-4 = 3 (x-2)

3; 9 is 8 to -4

step-by-step explanation:

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.
