The table
shows the total number of
kilometers Mr. Jackson drove to and from
work during the first 3 days of the week.
Copy the table and use the pattern to extend
it to Sunday. Explain how the total number
of kilometers changes as the number of the
day changes. |

For
each equation, find the values of y when x = –2, when x
= 0,
and when x = +2. |
| | 1.
y
= x
+ –4 | 2.
y
= +6 – x | 3.
y
= x
– +1 |
4.
y
= –2 + x |
| | 5.
y
= x
+ +6 | 6.
y
= –7 – x | 7.
y
= x
– +5 |
8.
y
= –9 + x |
|
| Graph each
equation. First make a table using x-values of –2, 0, and
+2. |
| | 9.
y
= x
+ +1 | 10.
y
= x
+ –2 | 11.
y
= –3 + x | 12 .
y
= +1 – x |

Darrell
runs 6 miles each day. To find how far Darrell runs
in 4 days, use the equation y = 4x,
where x is the number
of miles Darrell runs each day. |
