**Answer:
**

a) Line M

b)Line M

c)y=1/2x+2

**Step-by-step explanation:
**

a) Line M has a greater y-intercept since its y-intercept is at (0,2) while Line N's y-intercept is at (0,1)

b) Line M has a greater slope since its line is steeper

c) Use the formula y=mx+b

Use the points ( 0,1) and (-4,-1)

m(slope)= y2-y1/x2-x1

m= (-1-1)/(-4-0)

m=-2/-4

**m=1/2
**

substitute

(0)=1/2(-4)+b

**2=b(y-intercept)
**

**y=1/2x+2
**

2p=p(1+0.055/2)^2t

t=(log(2)÷log(1+0.055÷2))/2=12.8 years

multiply the 7 (the denominator), and the 6 (the whole number). To this product, add the 4 (the numerator)

giving 46, to form the new numerator, and use the 7 as the new denominator.

So, 6 4/7 as an improper fraction is 46/7

Pamela: x-5

Jiri: x

2x-5=55

2x=60

x=30

Remember x is Jiri but Pamela is (x-5). so, 30-5 is 25.

Jiri is 30 years old and Pamela is 25.
