Identity whether the following points are collinear . (2 , 3 ) (4 , 7 ) (8 , 11 )

not collinear points

Step-by-step explanation:

If the points are collinear ( lie on the same line ) then the slopes between adjacent points will be equal.

Calculate the slope m using the slope formula

m =

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 7)

m = = = 2

Repeat with (x₁, y₁ ) = (4, 7) and (x₂, y₂ ) = (8, 11)

m = = = 1

Since the slopes are not equal then the points are not collinear

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
