4. The data in the table are linear. Use the table to find the slope. (1 point)
x: 2|4|6|8 |
y: 1|-2|-5|-8|
3/2
-3/2
-2/3
2/3
NO CLUE:(
sorry!
7. Find the slope of a line that is parallel to the line containing the points (3, 4) and (2, 6). (1 point)
m = 1
m = 2
m = –2
m = 1/2
8. Find the slope of a line that is perpendicular to the line containing the points (–2, –1) and (2, –3). (1 point)
m = –2
m = 2
m = -1/2
m = –1
NO CLUE!:(

How can you have NO CLUE about finding the slope of a line between two points?
The slops is the change in y divided by the change in x. SO, between the two points (3, 4) and (2, 6),
y changes from 4 to 6, or +2
x changes from 3 to 2, or -1
m = 2/-1 = -2
Similarly for #8
Similarly for the #4 table. Watch the changes in x and y. They must all be the same from point to point for a straight line.

ok, i overthought that! oops!
thanx Steve!:)
thanx Steve!:)
so #8 is -1/2 right?
ill post what i think on #4 in a sec
ill post what i think on #4 in a sec
and #4 is 2/3.....
