PLSSS HELP! what is the slope-intercept equation of the line???

y = 2x + 3

Step-by-step explanation:

( 0, 3) and (-1, 1)

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

m= (1 - 3)/( -1 - 0)

m = (-2)/(-1)

m = 2

y - y1 = m (x - x1)

y - 3 = 2(x -0)

y - 3 = 2x + 0

y = 2x + 3

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.
