3. What is the y-intercept of the line
5x – 3y = 15? Write your answer as an ordered
pair.

(0, -5)

Step-by-step explanation:

For Y-intercept: put X = 0

5x-3y=15

-3y=15-5x

3y=-15+5x

y=-5+5/3x

y=5/3x-5

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.
