Please help me i have no clue what to do

Your suppose to plot the numbers above by the x and y axis

Step-by-step explanation:

Answer & Step-by-step explanation:

The vertical line test is used to determine if a given relation is a function.

How it works:

You can use anything that has a straight edge, usually a pencil. Hold it up to the graph at multiple points vertically.

Now, if the pencil crosses over two points, the relation is not a function. If you hold the pencil to the graph and it doesn't cross over two points, then the relation is a function.

If you hold a pencil to the graph vertically at each given point, the pencil does not cross over two points. Therefore, the relation is a function.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°
