c. y=-4x+3
D. y=-x=8

6.find the slope of the line through (6,2) and (4,-2)
A.0
b. half
c. unidentified
D. 2

Answer 1

here are my answer of what I think
1.d
4.c
6.b

Answer 2

3.

Answer c

Becouse :

For x = - 4

y = 2 x – 3 = 2 * ( - 4 ) - 3 = - 8 - 3 = - 11

4.

Answer d

If your expression mean y = - x + 8


6.

m = ( y2 - y1 ) / ( x2 - x1 )

In this case :

x1 = 6 , x2 = 4 , y1 = 2 , y2 = - 2


m = ( y2 - y1 ) / ( x2 - x1 ) = ( - 2 - 2 ) / ( 4 - 6 ) = - 4 / - 2 = 2

Answer d.

Answer 3

tnx so much :)
