Please explain how.

Answer 3

If we first solve for 'y' we get:\[y=1.5x+2\]
From this we can see that:
y is not constant, eliminating c.
y is a function of x, eliminating b
the slope is positive eliminating d.
a is the only one left.

Check by picking an 'x' on a, say x=0 and plug in \[y=1.5(0) +2 = 2\]
This checks out.

Check again by picking x=2 then \[y=1.5(2)+2=5\] Checks again.
