I am sure you have a good excuse for starting so late "need by end of day".  I can provide some help by helping with no. 2.  First you can see that the y intercept is -3 because x=0 as shown by the table.  Next calculate the slope by dividing the change in y by change in x.  This information is available from the table, I would use the first two points on the table.

Y=-3 the next y is 2 giving you a difference of -5
x = 0 the next x is 1, giving you a difference of -1   
Now you can calculate slope m, you  already have the y intercept.
