The first thing is the slope
y = 1/2 x + b is the new line. Now we must solve for b
2 = 1/2 (-2) + b
2 = -1 + b
3 = b
The new line is 
y = 1/2 x +3

I answered the question 3x-y=5 but is there a different way to answer this?
Svet_ta [14]

Step-by-step explanation:

Hi,

I agree with what you did. You could also add y on both sides and get 3x = y + 5 and then divided by three to get...

x = 5 + y /3

(the 5 and y are being divided by 3)

But that's just complicated, it works, but it's complicated. What you did is correct and what I gave you is the value of x, but I'm 100 percent sure yours is correct.

Hope this helps

A cheetah ran 230 feet in 1.932 seconds. What is the cheetah's speed in miles per hour?
Bumek [7]

Answer:

The answer to your question is speed = 81.5 mi/h

Step-by-step explanation:

Data

distance = 230 ft

time = 1.932 s

speed = ? mi/h

Process

1.- Convert the distance to mi

                1 mile ----------------- 5280 ft

                 x        ----------------- 230 ft

                 x = (230 x 1) / 5280

                 x = 0.044 mi

2.- Convert time to hours

                 1 h    ------------------ 3600 s

                  x      ------------------ 1.932 s

                        x = (1.932 x 1) / 3600

                        x = 0.00054 h

3.- Calculate the speed

speed = distance / time

-Substitution

speed = 0.044/ 0.00054

-Result

speed = 81.5 mi/h
