Question

Show that points A(-3,-2),B(3,1), and C(5,2) lie on a straight line​

Answer 1

Answer:

Step-by-step explanation:

If A, B, and C are on the same line, they have the same slope.

k is slope.

k(AB) = $\frac{(1+2)}{(3+3)} =\frac{1}{2}$;

K(BC)=$\frac{2-1}{5-3} =\frac{1}{2}$;

So k(AB)=K(BC)
