HELP PLS GEOMETRY SLOPE
2 answers:
Answer:
y = - 2x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (4, - 3) ← 2 points on the line
m = =
= - 2 , thus
y = - 2x + b ← is the partial equation
To find b substitute either of the 2 points into the partial equation
Using (2, 1 ) , then
1 = - 4 + b ⇒ b = 1 + 4 = 5
y = - 2x + 5 ← equation of line

Alright, lets get started.
Missing number fom the series : 9, ..... , 6561, 43046721
43046721 is square of its previous number 6561, means
It means the missing number will be square of its previous number
Means , so missing number is 81. : Answer
Next : one number is 2 more than 3 times another. their sum is 22. find the numbers.
Suppose one number is x and second number is y
As per given equation, ......equation (1)
Their sum is 22 means, .......equation (2)
Putting the value of x from equation1 into equation 2
Subtracting 2 in both sides
Means numbers are 17 and 5. : Answer
Next : the missing number in the series 1, 4, 27,____, 3125 is
1 could be written as 1
4 could be written as
27 could be written as
So , next number would be
Next one is
So, the missing number is 256 : Answer
Next : the next number in the series 3, 4, 6, 7, 9, 10 is
After 3,4 (5) is mising, 6, 7 (8) is missing, 9, 10 (11) will be missing
So, next number will be 12. : Answer
Next : a farmer is planting a straight row of crops with 3 feet between each plant. if 23 are planted, what is the distance between the first and last plant?
Between 2 plants, the distance is =
Between 3 plants, the distance is =
So, between 23 plants, the distance is =
hene the distance between first and last plant woule be 66 feet. : Answer
