Step-by-step explanation:

Equation of straight line: y=mx+b

Given slope=2, hence m=2

y=2x+b

Replace y and x values as stated in the question (-1, -2)

(-2)=2(-1)+b

-2+2=b

b=0

rewrite the equation:

y=2x+0

y=2x

For 3) a solid line is used when the equation is <= or => while dotted line is for when the equation is < or >

Could you elaborate on question 2? I dont quite get what the question is asking for

1. (section 2.1) Bungee jumping: Jimmy jumped off the Tallahatchie Bridge, 100 ft above

Tems11 [23]

Answer:

18.4 ft per second.

Step-by-step explanation:

Bungee jumped off the Tallahatchie Bridge, which is 100 ft above the water surface.

And after 5 seconds he was at 8 ft above the water surface.

Therefore, in total 5 seconds, he descends by total ( 100 - 8 ) = 92 ft altitude.

Hence, the average rate of change of his altitude is given by

$\frac{\textrm{Total altitude change}}{\textrm{Total time taken}} = \frac{92}{5} =18.4$ feet per seconds. (Answer)
