What is the slope of the line passing through the points (-5,7) and (-3,5)

Slope of  the line passing through the points (-5,7) and (-3,5) is -1.

Step-by-step explanation:

slope of line passing through point (x1,y1) and (x2,y2) is given by

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

In the problem given  points are (-5,7) and (-3,5)

using the formula for finding slop ewe have

m = (-3-(-5))/(5-7)

=> m = (-3+5)/-2

=> m = 2/-2

=> m = -1

Thus, slope of  the line passing through the points (-5,7) and (-3,5) is -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.
