The constant terms are: -14, and +2
Step-by-step explanation:
We can write
X=-2,-1,0,1,2
And the equation is y=3x+4-------(1)
First we should be put all the value in equation (1)
y=2,1,4,7,10
And the answer will
(x, y) ={ (-2,2),(-1,1),(0,4),(1,7),(2,8)}
X - the percent of increase

The percent of increase is approximately 23.8%.
The asymptote is the line the graph comes close to but never touches, so if you graph it out you should be able to see it! Sorry I couldn't help any more but good luck
