What is an
equation of the line that passes through the points (-2, 1) and (4,7)?

The answer is y=6x-10

Step-by-step explanation:  (-2, 1) and (4,7)

y2-y1                                  y=mx+b

x2-x1                                  1=6(-2)+b

7-1= 6                                 1=-11

4-(-2)= 6                           -11 =-11

                                         -10

The slope is 6

(3x-8) or (3x+8)

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.
