Determine whether the three points are collinear if
,4), q(-2,-1), r(1,14)

see explanation

Step-by-step explanation:

If the 3 points are collinear then the slope of PQ should equal the slope of QR

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = P(- 1, 4) and (x₂, y₂ ) = Q(- 2, - 1)

= = = 5

Repeat using

(x₁, y₁ ) = Q(- 2, - 1) and (x₂, y₂ ) = R(1, 14)

= = = 5

Since the slopes of the 2 segments are equal then the 3 points are collinear.

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p
