Question

Which equation is represented by the table?
x y (x, y)
0 –2 (0, –2)
1 1 (1, 1)
2 4 (2, 4)

A.
y = 3x – 1

B.
y = –2x – 3

C.
y = 3x – 2

D.
y = –2x + 3

Answer 1

The number that is not in front of a pronumeral in relations is the y intercept ( where x=0). And with that you should be able to get the answer.

Answer 2

I have no idea how to even start this

Answer 3

Ok.
The first thing you have to do when finding the equation to a linear graph is to find the gradient. This is done by.... Where m is the gradient.
