solution:
we know that ,
u.v = ΙuΙ ΙvΙcosθ
here,
θ =60° (since the given triangle is equilateral triangle)
u.v = ΙuΙ ΙvΙcos60°
= 1 x 1 x 1/2
u.v = 1/2
now, u.w = ΙuΙ ΙwΙcosθ
= ΙuΙ x cos(60x2)
u.w = -1/2

Answer: y = 4x
Step-by-step explanation: Slope intercept form is y = mx + b where m is the slop and b is the x intercept
We can solve for slope using the given points
(2-1)/(8-4) = 1/4, thus m = 1/4
y = 1/4x +b
Now to solve for b, we can just plug in one of the points to see what makes b work
1 = 4*(1/4) + b
1 = 1 +b
b = 0
