-4 is the distance between -4 and -8
First, we must determine the slope of the line. The slope can be found by using the formula:
m
=
y
2
−
y
1
x
2
−
x
1
Where
m
is the slope and (
x
1
,
y
1
) and (
x
2
,
y
2
) are the two points on the line.
Substituting the values from the points in the problem gives:
m
=
−

Next, we can use the point-slope formula to get an equation for the line. The point-slope formula states:
(
y
−
y

)
=
m
(
x
−
x
1
)
Where
m
is the slope and
(
x

y

)
is a point the line passes through.
Substituting the slope we calculated and the first point from the problem gives:
(
y
−

)
=

(

)
The standard form of a linear equation is:
A
x
+
B
y
=
C
Where, if at all possible,
A
,
B
, and
C
are integers, and A is non-negative, and, A, B, and C have no common factors other than 1
We can now transform the equation we wrote to standard form as follows:
y

Answer:
16
Step-by-step explanation:
Answer:
It would be the first option.
Step-by-step explanation:
minus 9 from both sides to get a -3
so z≤-3
A good trick I learned was which ever way the arrow is pointing (in this case left) is the way the line will go.
Answer:
47, 49, 51, 53
Step-by-step explanation:
I don't know how your teacher wants you to do it, but the formula for odd integers in this case would be (n+1) + (n+3) + (n+5) + (n+7) = 200.
The four odd integers are represented by each set of parentheses. If we find n, we can add 1, 3, 5, and 7 to it to get the four numbers you're looking for.
If we subtract all of the constants from the left side and add all every n, we get 4n = 184. We then divide both sides by 4, and the answer is n = 46.
(n+1) = 47, (n+3) = 49, etc.
Hope this helps!
