A student volunteered to explain to the class how to graph a line. The problem that was
given to her was:
Graph:
The student said that the y-intercept is 1, so plot a point at (0,1). The slope is
so from
(0,1) go over to the right 2 and up 3 to make another point at (2,4). Draw a line through
the points.
