What is the equation of the line that passes through the point (2,-4) and has a
slope of 2?

y = 2x - 8

Step-by-step explanation:

Point(2 , -4) ; slope = 2

Point- slope form:

y - y1 = m(x - x1)

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

y + 4 = 2x - 2*2

y + 4 = 2x - 4

     y= 2x - 4 - 4

     y = 2x - 8

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
