I have walked you through how to do these step by step, did you not understand what I was saying?
OpenStudy (anonymous):
no i said it was answer B
OpenStudy (anonymous):
for first two
first write in the form y=m x+c
if m>o positive rate of change
if m<0, negative rate of change.
OpenStudy (sleepyjess):
Are you saying no, you did not understand what I was telling you?
OpenStudy (anonymous):
for third and fourth as x increases see if y increases or decreases.

If you can't show us your work, then overall, it is harder for use to teach you.
OpenStudy (sleepyjess):
The slope formula is \(\dfrac{y_2-y_1}{x_2-x_1}\). To use this pick any 2 points given for number 4.
OpenStudy (anonymous):
2 and -8
OpenStudy (sleepyjess):
2, -8 is one coordinate, pick another
OpenStudy (sleepyjess):
2, -8 is going to be \(x_1,~y_1\)

3 and -7
OpenStudy (sleepyjess):
Ok, 3, -7 is going to be \(x_2,~y_2\). Now substitute these into the formula and solve.
OpenStudy (anonymous):
ok lagging out
OpenStudy (sleepyjess):
Can you show me what you get once you use that formula?
OpenStudy (anonymous):
ill try
