Describe what happens to the graph of y=3x+4 when the slope is changed to 1/3

Answers


The graph is still a straight line, it still cuts the y-axis at the point y=4 ,
and it still slants up from left to right.

But it becomes a lot less steep.  The original line only had to go 4 inches
to the right in order to rise 1 foot.  The new line has to go 3-feet to the right
in order to rise 1 foot.
