Answer 1

Just find the slope

Answer 2

so the first has (-1+1)/(1-0)=0

Answer 3

second rate is 7

Answer 4

hoird rate is -15/5=-3

Answer 5

put it in \(y=mx+b\) form. The \(m\) is the rate of change.

Answer 6

the last has rate of 4

Answer 7

so B

Answer 8

not needed
y=ax+b a is the slope
ax+by=c -a/b slope

Answer 9

on grath this is simple onne just count by y 4 by x 1 so 4
YES B!

Answer 10

B

Answer 11

thanks
