What is the value of m, the points (2,3),(3,6)and (m,12) are collinearPlease y'all help me out

m = 5

Step-by-step explanation:

Since the points are collinear, they all lie on the same line and have the same slope between them.

Calculate the slope m using the slope formula

m =

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (3, 6)

m = = = 3

Now calculate the slope using 2 other points and equate to 3

(x₁, y₁ ) = (3,  6) and (x₂, y₂ ) = (m, 12)

m = = = 3 ( multiply both sides by m - 3 )

6 = 3(m - 3) ← divide both sides by 3

2 = m - 3 ( add 3 to both sides )

5 = m

m =  5

Step-by-step explanation:

P(2, 3)  ; Q(3 ,6)  ; R(m , 12)

Slope of QR = slope of PQ

Slope of PQ:

Slope of QR:

Slope =

Slope of PQ = slope of QR

        3m = 6 + 9

        3m = 15     {Divide both sides by 3}

     3m/3 = 15/3

m = 5

the image of (6, 9) under a dilation is (4, 6). the scale factor is
