2. Which point lies on the graph represented by the equation 3y + 2x = 8? (1) (-2,7)
(2) (0,4)
(3) (2,4)
(4) (7,-2)

4) (7, - 2)

Step-by-step explanation:

A point that lies on the graph of 3y + 2x = 8 is a solution of this equation. Substitute each ordered pair into the equation to find the correct answer.

1: (-2, 7)

59 is not equal to 8 so this answer is incorrect.

2: (0, 4)

12 is not equal to 8 so this answer is incorrect.

3: (2, 4)

16 is not equal to 8 so this answer is incorrect.

4: (7, - 2)

This ordered pair satisfies the equation so this is the correct answer.

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°

hope this
