Question

Points A, B, and C are colinear.IABWhat is the slope of BC in simplest form?Enter a + or - sign. [?]

Answer 1

`m=-(1)/(3)`

1) Considering the slope as the rise/run. Let's enumerate that grid

Enumerating the grid, we can state that A( 2,5), B(5,4), and C(11,2)

2) So now, let's find the slope of BC

`m_(BC)=(2-4)/(11-5)=-(2)/(6)=-(1)/(3)`

Since those points are colinear, the slope of BC = slope of AB for the slope is a measure of how steep is the line.
