Question

Review what you know about graphs as you complete parts (a) through (d) below.

a. Find the equation of the line graphed at right.

b. What are its x- and y-intercepts?

c. On your own graph paper, graph the line.

d. On the same set of axes, graph a line that is parallel to the line graphed at the right and that goes through the origin (0, 0). Find the equation of this new line.

Answer 1

A. Y=-2x+1
B. X(1/2,0), Y(0,1)
C. Graph the line same way as it is on this graph
D. Y=-2x. Parallel lines have the same slope and since it goes through the origin, it does not have a y-intercept.
