## Investigation of Equations

by
# Jim Wilson

The equations y = x - 2 and
y = x - 5 will cross the x-axis at -2 and -5 respectively. They
will have a slope of 1.

If the product of the two **equations
**was taken we would get the same graph with one equation:

The equation is

Rewrite this equation by expanding

What would happen to the graph
if the coefficient of y was changed in this equation?
