x: 2, 7, 4, 10, 20
y: 2, 4.5, 3, 6, 11
x: 3, 6, 8, 10, 22
y: 13,31, 43, 55,127

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
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.
