Need help don’t know what to do I’m confused

-x + y = 8

Step-by-step explanation:

Slope =

          =

slope = 1, m represents the slope

y - y1 = m(x - x1)

choose any point ( -1, 7 ) or ( 2,10 )

y - 7 = 1( x + 1 )

y - 7 = x + 1

-x + y = 8

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

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
