Question

Which equation best describes the relationship between x and y in this table?

x y
0 -4
4 -20
-4 12
8 -36
y = - x/4 - 4
y = - x/4 + 4
y = - 4x - 4
y = - 4x + 4

Answer 1

sorry 0-8 is the table

Answer 2

x and y is the table sorry

Answer 3

so last 4 equations are multiple choices ?

Answer 4

yes

Answer 5

okay what's the formula to find slope ??

Answer 6

(x1, y1) and (x2, y2).

Answer 7

okay those are order pair
formula to find slope ? do you know ???

Answer 8

nope.

Answer 9

\[\huge\rm m = \frac{ y_2 - y_1 }{ x_2 -x_1 }\]
formula to find slope
now use those two order pair replace variables by their values

Answer 10

okay.

Answer 11

C. y = - 4x - 4 ?

Answer 12

okay what does -4 represent in the equation ?

Answer 13

X

Answer 14

what is the slope of that equation ??

Answer 15

umm..I think (x1, y1) and (x2, y2).

^^^ do it

Answer 22

okay

Answer 23

idk I got confused lel

Answer 24
