yy-intercept is -44

And for every xx-value there would be an increase of 33 in the yy value

Explanation:

Choose xx values and work out the yy values.

x rarr yxy
0, -40,4
1, -11,1
2, 22,2
3, 53,5
4, 84,8
5, 115,11
6, 146,14
7, 177,17
8, 208,20
9, 239,23
10, 2610,26

Now plot the points and join them with a straight line.

Whenever there's an increase in the xx by 11,. there will be an increase in yy by 3.3.
