HELP What is an equation for the parallel to y= 3x-1 that passes through (-9,-2)

The line parallel to this equation would be y=3x+25

Step-by-step explanation:

A parallel line has the same slope but a different y-intercept (so just ignore the "-1" in the equation )  Our goal is to find the y-intercept ("b")

We will start with  

y=3x+b, plug in (-9,-2) for the x and y

-2=3(-9)+b

-2=-27+b,    add 27 to both sides

-2+27=-27+27+b    (the 27's on the right side cancel side)

b=25

our new equation is y=3x+25

the mean and mad

step-by-step explanation:

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.
