Step-by-step explanation:
A graph quickly answers this question.
__
The given points have a horizontal difference of 4-(-1) = 5 and a vertical difference of 3-(-2) = 5, so the slope of the line between them is ...
m = Δy/Δx = 5/5 = 1
The point-slope form of the equation for a line can be written ...
y = m(x -h) +k . . . . . for slope m through point (h, k)
Using the first point and the slope we found, we can write the equation as ...
y = 1(x -(-1)) +(-2)
y = x -1 . . . . . . . . . simplify; this is the equation of the line
__
When we try the third point in this equation, we get ...
y = 3 -1 = 2 ≠ 1 . . . . . the third point is not on the line
Answer:
The number x = 3
Step-by-step explanation:
Let 'x ' be the positive integer
Given data If the sum of five times a number and two times the same number and the same number is increased by 4 and the result is 25
sum of five times a number is 5 x and same number two times is 2 x and increased by 4 (addition) then result is equal to 25
so finally 5 x +2 x +4 = 25
7 x + 4 = 25
subtracting '4' on both sides , we get
7 x = 21
dividing '7' on both sides, we get
Therefore the number is x = 3
<u>Verification :</u>-
5 x +2 x +4 = 25
substitute x = 3 in above equation
15+6+4 = 25
25 =25
<u>Final answer</u> :-
The number is 3
