Can I get some help please??

1. the y intercept is supposed to be -1 not 1

2a. The slope is a positive slope, its supposed to be a negative one.

2b. Jake wrote a slope of 1/4 instead of -1/4

Step-by-step explanation:

For the second part the point (12,4) is not on the graph.

Plug in the x and y values into the equation y = (-1/4)x - 1

So 12 = (-1/4)(4) - 1

12 = (-1) - 1

12 = -2

12 does not equal 2. Therefore, the point (12,4) does not lie on the graph above.

Hope this helps!

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.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
