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:

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints
