Question

Consider the 4 points A(1,5), B(-4,6), C(0,0), D(-12,12). Find the gradients of the lines:

(a) AB;

(b) CD;

(c) BD.

Answer 1

One of the most basic concepts in this topic is "finding the slope between two points"
Your text and notes MUST contain the steps

I will do the first one, you do the rest
slope = (y2-y1)/(x2-x1)
= (6-5)/(-4-1)
= 1/-5 or - 1/5
