Question

(-2,-4) (2,4) what is the answer in slope intercept form

Answer 1

Answer:

y = 2x

Step-by-step explanation:

We can find the slope

m = (y2-y1)/ (x2-x1)

    = (4--4)/(2--2)

     = (4+4)/(2+2)

   = (8/4)

   = 2

We can use the point slope form of the equation

y-y1 = m(x-x1)

y--4 = 2(x--2)

y+4 = 2(x+2)

Distribute the 2

y+4 = 2x+4

Subtract 4 from each side

y+4-4 = 2x+4-4

y = 2x

y+2 = 2x+4
