Answer:

y = -2x -1

Step-by-step explanation:

slope intercept form is y = mx +b

m = slope, b = y intercept

point is given as ordered pair (x,y)

plug in slope into y=......

y= -2x+b

plug in the point

3 = -2 * (-2) + b

3= 4 +b subtract 4 on each side

b = -1

y = -2x -1

Answer:

$6.21\times 10^{-5}\ \text{light years}$

Step-by-step explanation:

The distance light travels in one year is known as a light year.

$1\ \text{light year}=5.87\times 10^{12}\ \text{miles}$

The closest that Earth ever gets to Jupiter is $3.65\times 10^8\ \text{miles}$

$3.65\times 10^8\ \text{miles}=\dfrac{1}{5.87\times 10^{12}}\times 3.65\times 10^8\ \text{light years}\\\\=6.21\times 10^{-5}\ \text{light years}$

Hence, the distance it will take light to travel from Earth to Jupiter at this distance is $6.21\times 10^{-5}\ \text{light years}$

Step-by-step explanation:

There is a total amount of vehicle of 100

which is good because now you can say 73% is cars 16% is small trucks 6% is large trucks and 2% motorcycle and 3% bicycle. Adding the trucks (small 16, large 6) gives us 24% so you can do 100% - 24% and get 74%. Thanks and goodbye!
