What is the equation of the line that passes through the point (1, 7) and has a slope of -1

The answer is

Step-by-step explanation:

To find an equation of a line when given the slope and a point we use the formula

where

m is the slope

( x1 , y1) is the point

From the question the slope is - 1

the point is (1, 7)

The equation is

We have the final answer as

Hope this helps you

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

it would rotate about 180 degrees.
