The following problems are in slope,point slope, and slope intercept forms of a line.
Could you check these thanks.
Find the slope intercept form of a line that passes through these two points (4,4) and (2,1)
Answer: y= 1/2x2
Find the slope intercept form of a line that is parallel to the line created in problem #1 and passes through the point ( 2,6)
Answer: y= 1/2x+4
Find the slope intercept form of a line that is perpendicular to the line created in problem #1 and passes through the point (1,3). What can you say about the relationship of this line and the line created in problem #2.
Answer: y= 1/2x+1/1/2
My response: I can say that is I used the same slope which is 1/2x

Math/Algebra do u know how to do slope intercept? 
Damon,
two points (4,4) and (2,1)
m = slope = (Y1Y1)/(X2X1)
= (14)/(2+4) = 3/6 = 1/2
then put either point in:
y = (1/2) x + b
1 = (1/2) 2 + b
1 = 1 + b
b = 2
so
y = (1/2) x + 2
I think you have a sign error in your answer for b
if parallel, same slope = (1/2)
y = (1/2) x + b
now the point in
6 = (1/2)(2) + b
6 = 1 + b
b = 5
so
y = (1/2) x + 5
then perpendicular
m = 1/(1/2) = 2
s
y = 2 x + b
3 = 2(1) + b
b = 1
so
y = 2 x + 1

Damon,
By the way, you can always check the answers by seeing if all the points fit the line you come up with.

Damon thank you ()() 
Alex,
Thank you very much you really Helped!

Alex,
I had the same homework to not like this but now I know how to do it thanks chico for posting a similar problem and thanks damon
