Answer 3

A positive rate of change means that as you go to the right on the x-axis (positive x), you go up on the y-axis (positive y).

Answer 5

ok

Answer 6

yeah the number 2,3,4 went down, so i asumed

Answer 7

For the first one, it will be easiest to see whether that is true if you rearrange the equation into slope-intercept form:
\[y = mx+b\]where \(m\) is the slope and \(b\) is the \(y\)-intercept
if \(m\) is positive, you have a positive rate of change
if \(m\) is negative, a negative rate of change
if \(m\) is 0, no change

Answer 8

so i know for a fact 3 and 4 are negative......

Answer 9

I didn't notice that you had chosen answers there, do I correctly read that as
