Answer 3

i think B btw

Answer 4

these are linear functions of x
what are the slopes of each line

Answer 5

\[y_1=7-\frac{ 1 }{ 4 }x \\ y_2=x+2 \\ x=4;y=6\]

Answer 6

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

Answer 7

yes thats correct
these will intersect once

Answer 8

okay so B is correct then "exactly once"
