I will need you to submit these answers within a copy of the questions.

The reason is that it would take 10 times as long, and would therefore exceed the number of hours in a day, for me to review asychronous submissions of student work by looking back and forth between two or more documents, or at different locations within the same document. I need the document to flow from question to response to question to response.

I also generally need to see your reasoning, not just your final answers. Without the reasoning it's often not possible for me to figure out where you went wrong. This is not a problem if you're seldom wrong, which judging from your work so far might well be the case.

y= .3f(x)

y= f(x)

y=f(x)-2

y=f(x)+4

2.

3. (-3, -5)

(1,3)

2= slope

4. -1.77 is th rise and -3.87 is the run

(y2-y1)/ x2-x1= slope

rise

run

slope

5. y= 2x+ -3

y= 2x+3

6.

7.x= distance

y= force

(2.9, .77)

(4.1, 1.04)

slope= .77-1.04/401-2.9

= -.225

8. -1.05cm/sec
