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).
yeah the number 2,3,4 went down, so i asumed
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
so i know for a fact 3 and 4 are negative......
I didn't notice that you had chosen answers there, do I correctly read that as
If so, those are correct
and also 2 is negative and 1 is positve so i am pretty sure i am correct
thank you for checking here is medal :)
i will tag u when i need more checking ;)
Thanks! Medals are great, a few thousand of them and about $3-4 gets me a cup of coffee at Starbucks :-)
yay! i hope u do get that much! lol
Perhaps if I found someone who works at Starbucks and who needs math help the conversion rate would improve in my favor :-)
