What is the equation of the graphed line in point slope form

y + 3 = (2/3)(x + 3)

Step-by-step explanation:

We can read the y-intercept directly from the graph:  (0, -1).  Another point on this line is (3, 1).  As we move from the point (0, -1) to the point (3, 1), x increases by 3 and y increases by 2.  Thus, the slope of this line is

m = rise / run = 2/3.

Starting from the general point-slope form of the equation of a straight line:

y - k = m(x - h), where (h, k) is a point on the line and m is the slope, we get:

y - [-3] = (2/3)(x - [-3]), or    y + 3 = (2/3)(x + 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.

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130
