Compare the graphs of lines A, B, and C at right.

Which line has the greatest slope? Justify your answer.
Hint (a):
Which line increases most sharply?
Answer (a):
Line A

What is the $y$ -value of line A when $x=2$ ?
Hint (b):
Locate line A and $x=2$ on the graph.
More Help (b):
What is the $y$ -coordinate of the point on the graph?

Compare the slopes of lines B and C.
Hint (c):
The lines are parallel. Parallel lines have the same change in $y$ for the same change in $x$ .

Coordinate plane with 3 increasing lines, passing through points, as follows: A: the origin and the point (2, comma 5). B: the points (0, comma 6), and (2, comma 7). C: the origin and the point (2, comma 1).
