The 2 is irrelevant, the 4 determines whether you round up or down. since the four is less than 5 you round down. ( if the number to the right is 5 or greater you round up, if it is less than 5 you round down
0.142 = 0.100 = 0.1

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).

0.142 ≈ 0.1

The point slope form of a line is written as y - y1 = m(x -x1)

Where m is the slope and x1 and y1 are the points on the line.

You are told the slope is 3 and the point is (2,-1/2)

x1 is 2 and y1 is -1/2

Replace those in the equation to get:

y- (-1/2) = 3(x-2)

Simplify to get the final answer:

y + 1/2 = 3(x-2)
