slope 4

y intercept 0, 4

Step-by-step explanation:

Slope: -1

y-intercept: (0, 9)

Step-by-step explanation:

The slope is -1 because -1x is the same as -x and the slope is the number before x. The y-intercept is (0, 9) because the y-intercept is what y is when x is 0 so y = -1(0) + 9 which equals 9.

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
