Answer:

y=-\frac{1}{2} x+1

Step-by-step explanation:

To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points

SO

\frac{y_{1}- y_{2}}{x_{1}- x_{2}} \\\\=\frac{2-0}{-2-2}

=-\frac{1}{2} this is your slope

so now your equation is y=-\frac{1}{2} x but it isnt done yet if we plug in one of the points we will find the y- intercept.

SO we find our y-intercept is 1 so that makes our equation y=-\frac{1}{2} x+1

Hope this helps!

Pls make brainliest :)

Answer:

D

Step-by-step explanation:

step 1: find the slope

slope is 2/-4 = -1/2

then plug in the value for x to y, you get +1 for the y intercept

then it becomes y=-1/2x + 1

I hope this answer helped, and if it was correct, please mark this as brainliest! Thank you!

If I can walk 9673.6 meters in 5 hours. How far can I walk in 70 minutes. ( I need the work)
den301095 [7]

First, convert 5 hours into minutes:

5 hours 60 min

------------ * --------------- = 300 min

1 1 hr

Next, find the unit rate in m/min:

9673.6 m

--------------- = 32.24 m/min

300 min

Now find the distance you can walk in 70 minutes at this rate:

32.24 m

------------- * 70 min = 2247 meters (answer)

1 min

You could walk 2247 meters (to the nearest meter) in 70 minutes.
