The correct equation should look something like this:
y= -1x - 2

Consider the equation for a line:
y = mx + b,
Where ‘m’ is the slope
Where ‘b’ is the y-intercept.

From there you can plug in your known values for ‘m’ and ‘b’, and get the equation above. If you are still not convinced, I suggest you graph the function and observe its slope and y-intercept.

Hope this helps!

A rope is 250 centimeters long. You need the rope to be 1 1/2 meters long. How many centimeters should you cut off?
Drupady [299]
If you would like to know how many centimeters should you cut off, you can calculate this using the following steps:

1 1/2 meters = 3/2 meters = 1.5 meters = 150 centimeters

250 centimeters - 1 1/2 meters = 250 centimeters - 150 centimeters = 100 centimeters = 1 meter

The correct result would be 100 centimeters.

An airplane leaves Los Angeles and travels five hours to New YorkCity. The return trip travels along the same route and takes si
finlep [7]

The distance of the plane flies between the two cities is 1,113.75  miles

The formula for calculating the distance travelled is expressed as:

D = vt where:

v is the speed

t is the time taken

Given the following:

v = 99mi/hr

Total time taken = 5hr + 6.25hr

Total time taken = 11.25hr

Get the required distance

Distance = 99mi/hr * 11.25hr

Distance = 1,113.75miles

Hence the distance of the plane flies between the two cities is 1,113.75  miles
