You can't do 140 divided by 18
or it will end up like this <span>7.77777777778</span>
Answer:

Step-by-step explanation:
The point-slope formula is
. When knowing the slope of a line and a point it intersects, we can write its equation with that formula. Substitute
,
, and
for real values.
1) First, find
, or the slope. Use the slope formula
and substitute the x and y values of the given points. Then, solve:

Therefore, the slope of the line is -10.
2) Now, substitute the needed real values into the point-slope formula,
. Since
represents the slope, substitute -10 in its place. Since
and
represent the x and y values of a point the line crosses, choose any of the points given and substitute its values into the formula. (Either one is fine, they both equal the same thing. I chose (2,3).) This will give the following answer and equation:

Answer: The Perimeter of the rectangle, P= 16v −24w
Step-by-step explanation:
Perimeter of a rectangle = 2( L +W) = 2L + 2W
The width of a rectangle is given as (3v-3w) centimeters,
its length is given as (5v-9w) centimetres
The Perimeter,P will now be = 2L + 2W
P=2( 3v-3w) + 2( 5v-9w)
P=6v −6w + 10v - 18 w
adding like terms
P=6v + 10v −6w −18 w
P= 16v −24w
Answer:
-2
Step-by-step explanation:
The slope of a line is given by
m = (y2-y1)/(x2-x1)
= (-3 -5)/(2- -2)
= -8/(2+2)
-8/4
-2
