Write the equation of the line:
(0,3); slope = -2

y = -2x + 3

Step-by-step explanation:

The point-slope form of the equation of a line is:

y - k = m ( x - h )

Being m the slope and (h,k) is a point through which the line passes.

We are given the point (0,3) and the slope m=-2

Substituting:

y - 3= -2 ( x - 0 )

Operating:

y - 3= -2x + 0

y - 3= -2x

Adding 3:

y = -2x + 3

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.
