What is the slope of the line whose equation is −48=2x−8y? enter your answer in the boxes.?

The slope is m=1/4.
Here's how to solve...

Isolate y for -48 = 2x-8y:
2x-8y = -48

Subtract 2x from both sides:
2x-8y-2x = -48-2x
-8y = -48-2x

Divide both sides by -8:
-8y/8 = -48-2x/8
y= 1/8(2x+48)

y=1/4x+6

Line equation form is y=mx+b, in which the slope is m.
m=1/4

Hope this helped! :)

The answer is 225 miles per 4.5 hours. hope this ; )
