x:   2,  4,   7,    10,  20

y:   2,  3,   4.5    6,   11

 

The slope between any two points  is constant  and equals 1/2.....for instance, the slope between the first two points =

 

[ 3 -2 ] / [ 4 - 2]  =  1/2

 

Using this and one of the points - I'll use the first one - we can write the equation of a line thusly

 

y - 2  = (1/2)(x - 2)

 

y  = (1/2)x - 1 + 2

 

y = (1/2)x + 1

 

 

 

x:   3,   6,   8,  10,  22

y:  13,31, 43, 55,127

 

The slope between any two points =   [31 - 13] / [ 6 - 3]  =  18/3  = 6

 

In similar fashion to the first problem, we have

 

y - 13 = 6 ( x - 3)

 

y - 13 = 6x - 18

 

y = 6x - 5

Thank you guy's. I would have gotten an F in math without your help.

Don't worry.....we get "F's"  in math all the time....LOL!!!!!

If I get F's in math I could loose being able to actually debate in tournaments. I don't think my grandma would be to excited to see an F on math. But really thanks for helping me I have actually been helping other people with their problems so I will probably back on tomorrow.
