Answer to Question #913 in Geometry for Camyka Moore

Question

What is the slope of the line through the points (0, 3) and (3, 0)?

Answer 1

We can write the euqaltion of the line in such form
y = mx +b, where m is the slope.
For the point (0,3) : 3 = 0*m + b;
For the point (3,0) : 0 = 3*m +b;

Solving this system of equations would give us the answer: m = - 1.
