Question 1050349: I have been learning about graphs and linear equations but i am having a tough time doing 3 questions
It is hard to explain so heres a idea
Queastion: write a linear equation relating x and y for each table
1.
X | 0 | 3 | 6 | 10 |
Y | 2 | 8 | 14 | 22 |
2.
X | 0 | 3 | 6 | 10 |
Y | 20 | 8 | -4 | -20 |
3.
X | 2 | 4 | 6 | 8 |
Y | 5 | 8 | 11 | 14 |
Please help me i tried. For 1. I got Y=2x + 2

1.
(0,2)
(3,8) m = -6/-3 = 2 m =%28y%5B1%5D+-+y%5B2%5D%29%2F%28x%5B1%5D+-+x%5B2%5D+%29
y - 2 = 2(x-0) ***Using point-slope form, y+-+y%5B1%5D+=+highlight_green%28m%29%28x+-+x%5B1%5D%29
y = 2x + 2 Good Work
2.
(0,20)
(3,8) m = 12/-3 = -4
y - 20 = -4(x-0)
y = -4x + 20
3.
(2,5)
(4,8) m = -3/-2 = 3/2
y - 5 = (3/2)(x-2)
y = (3/2)x +2
