By finding the gradient of this line. with working and answer.

The gradient is 1/2.

Step-by-step explanation:

y = 1/2 x + 2 is an example of the general form y = mx + c where m is the gradient of the line.

So the gradient = m = 1/2.

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.

if you explain the the question more correctly i might be able to answer this better
