Find an equation for the line below

please i need this asap i can’t get it right

rise/run = slope

slope = 2/4 = 1/2

y = 1/2x +b

now, choose a point on the line and substitute y for the y coordinate and x for the x coordinate > i will use (1, -1)

-1 = 1/2(1) + b

-1 = 1/2 +b

subtract 1/2 from both sides

-3/2 = b

y = 1/2x - 3/2

y = 1/2x - 3/2

General Formulas and Concepts:

Order of Operations: BPEMDAS

Slope Formula:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define coordinates:

(-3, -3)

(1, -1)

Step 2: Find slope m

Step 3: Find y-intercept b

Step 4: Write linear equation:

Plug in the newly found b into the equation.

y = 1/2x - 3/2

the answer is b; false. 2 dimensional things are a lot more different from 3 dimensional things.

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
