Help me get this correct if u do i will mark if i can

The correct option is C. Y=1/2x+2

Step-by-step explanation:

You can use desmos graphing calculator to help you with these type of problems. Here is the link.

1/2x + 2

Step-by-step explanation:

From graph, we see the line passes through (-4,0) and (0,2)

So..the equation of the straight line is

X/-4 + Y/2 = 1

Or, 2y - x = 4

So, y = 1/2x +2

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
