Linear Equation Generator

By Benjamin Joffe on Dec 5, 2003

This Linear Equation generator asks you to find the relationship between X and Y. This is a straight line formula in the form of Y=MX+B where M is the slope and B is the y-intersect.

This maths question generator asks you to find the relationship between X and Y. This is a linear fucntion in the form of Y=MX+B where M is the gradient and B is the y-intersect.

X	1	2	3	4	5
Y

Y = X +
