The equation that represents the data in the table is y = 4x – 2.

Solution:

Take any two point from the table.

Let the points taken are (0, –2) and (3, 10).

x_1=0, y_1=-2, x_2=3, y_2=10

Slope of the line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{10-(-2)}{3-0}

$m=\frac{12}{3}

m = 4

Using point-slope formula,

y-y_1=m(x-x_1)

y-(-2)=4(x-0)

y+2=4x

Subtract 2 from both sides, we get

y = 4x – 2

The equation that represents the data in the table is y = 4x – 2.

Find the slope of the line through these pair of points.<br><br> (12,-18) (-15,-18)
zysi [14]
The slope, m, is given by the equation m = (y2-y1)/(x2-x1), where (x1, y1) and (x2, y2) are points on the graph. Thus:
m = (-18-(-18))/(-15-12)
= (-18+18)/-27
= 0/27 = 0
Therefor the slope is 0

A room has dimensions of 8 mx 6 mx 4 m.
natali 33 [55]

Answer:

Price of paint = Rs 16,640

Step-by-step explanation:

As 3 dimensions are given so the third one must be for ceiling.

So in this case, we can find area as follows:

Area = 2(length * width) + 2(length * height)+ 2(height * width)........eq1

Lets say:

Length = 8m

Width = 6m

Height = 4m

So putting value in eq1 we get:

Area = 2(8*6) + 2(8*4) + 2(4*6)

Area = 2(48) + 2(32)+ 2(24)

Area =96 + 64 + 48

Area = 208 sq. m

Now for calculating price:

Price of paint = 208 * 80

Price of paint = Rs 16,640

I hope it will help you!
