Does anyone know how to do this that could help me?!

m= 0.5/1 we write it as -1/2 the rate of change.

So we now know the coordinates are (0.5, 1) we can input the rate of change as m being the slope.

So that m= -1/2 we want to write y = -1/2 * 0.5 x 2 but we start with x+b and show what the equal m and x values.

y = -0.5(x + b)

y = -1/2 * 0.5 + 1.25

y=1

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.
