Which best explains how you know that p(2,7) is on the same line as q(7,4) and r(12,1)

Step-by-step explanation:

if it has the same slope

the slope is

4-1=3

7-12=-5

slope=-3/5

4-7=-3

7-2=5

slope=-3/5

Step-by-step explanation:

If P(2, 7), Q(7, 4) and R(12, 1) are collinear, then the slope of PQ is equal to the slope of QR.

The formula of a slope:

Substitute:

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
