7. seven possible descriptions of lines are listed below.
i. positive slope
ii. negative slope
iii. y-intercept equals 0
iv. passes through the point (1, 2)
v. slope of zero
vi. positive y-intercept
vii. negative y-intercept
for each equation, list all of the descriptions i-vii that describe the
graph of that equation.
a. y=20
b. y=3 - 3x
c. y=2x + 3
d. y=5x - 3
e. y=2
in exercises 8-12, the tables represent linear relationships. give the
slope and the y-intercept of the graph of each relationship. then match
each of the following equations with the appropriate table.
y=5 - 2x
y= 2x
y=-3x - 5
y=2x-1
y=x+3.5
