which of the following is the equation of the line below
A rod of length 12 cm moves with its ends always touching the coordinate axes. Determine the equation ofthe locus of a point P on the rod, which is 3 cmfrom the end in contact with the x-axis.
type y = 1x + 1 into a graph. Where does this line cross the y-axis?
Notice that these two lines are now parallel (they run in the same direction without ever crossing). Think about the only change you made, and write the equation of another graph in the form y = mx + b that would also be parallel to these two lines?
