Question 62628
4. Find the midpoint between these points:
(4, 2) and (8, -1)
It's half way between the x values: (4+8)/2=6
and half way between the y values: (2+-1)/2=1/2
Therefore it is (6,1/2)
----------------------
5. Fill in the chart given this linear equation:
x + 7y = 4.
*Type all your work below the chart. 
x------ y=(4-x)/7
-2 ---- y=(4--2)/7=6/7
-1----- y=(4--1)/7=5/7 
0 ------y=(4-0)/7=4/7
1 ------y=(4-1)/7=3/7
2 ------y=?Can you do it?
----------------
6. Thelinear equation x = -13 graphs as a horizontal/vertical/diagonal line (choose the correct label and type it below).
Plot two points: (-13,0) and (-13,5)
Draw a line thru them
Now, can you answer the question?
Ans: vertical
