Find the equation of the straight line that has slope m = -6 and passes through point (2, -7)

MAXImum [283]

Answer:

y

=

3

2

x

+

1

Explanation:

To find the slope

(

m

)

of the straight line that passes through two points

(

x

1

,

y

1

)

and

(

x

2

,

y

2

)

apply:

(

y

1

−

y

2

)

=

m

(

x

1

−

x

2

)

In this example our two points are

(

0

,

1

)

and

(

2

,

4

)

Hence:

(

1

−

4

)

=

m

(

0

−

)

−

→

m

The equation of a straight line in slope

(

m

)

and intercept

(

c

)

form is:

y

=

m

x

+

c

In this example:

y

=

3

2

x

+

c

Since the point

(

0

,

1

)

is on this line

→

1

=

0

+

c

Hence,

c

=

1

∴

y

=

3

2

x

+

1

is our required straight line.

A rectangular prism with length 12 m , width 8 m & height 15 m , find its surface area .

Irina-Kira [14]

Answer: $792\ m^2$

Step-by-step explanation:

Given

The length of the rectangular prism is $l=12\ m$

width of the rectangular prism is $w=8\ m$

height of the rectangular prism is $h=15\ m$

The surface area of the rectangular prism is $2[wl+lh+hw]$

Put the values

$\Rightarrow 2[8\times 12+15\times 12+15\times 8]\\\Rightarrow 2[96+180+120]=2\times 396\\\Rightarrow 792\ m^2$

The surface area of the rectangular prism is $792\ m^2$
