Identify m and b. Hint: Rewrite each expression in the form y=mx+b. 1.3x=y+1
2.5x-5y=10

1. y = 3x - 1

m = 3

b = -1

2. y = x - 2

m = 1

b = -2

Step-by-step explanation:

1.

3x=y+1

3x -1 = y

y = 3x - 1

m = 3

b = -1

2.

5x-5y=10

-5y = -5x + 10

y = x - 2

m = 1

b = -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.
