Answer:

Step-by-step explanation:

The gradient of a line is the coefficient of x when the equation of the line is written in the form of y=mx+c.
Thus, gradient of given line=
.
The product of the gradients of perpendicular lines is -1.
(Gradient of line)(-3/2)= -1
Gradient of line

Substitute m=
into y=mx+c:

To find the value of c, substitute a pair of coordinates.
When x= -6, y= 8,

Thus, the equation of the line is
.

Step-by-step explanation:
Answer:
The required paint for a total of
is approximate 6 gallons
Step-by-step explanation:
we know that
To find how much paint would I need to buy to paint the walls of all three bedrooms, calculate the area of all three bedrooms
<em>Master Bedroom</em>
The area is equal to

<em>2 Bedroom</em>
The area is equal to

<em>3 Bedroom</em>
The area is equal to

The total area is equal to
A=A1+A2+A3

Approximate one gallon of paint covers 250 square feet
so
