pleaseee help how do i write an equation in slope-intercept form for the line with slope 1/3 and y-intercept -3?
Montano1993 [528]

Answer:

y=1/3x -3

Step-by-step explanation:

Slope intercept form  is y=mx+b, where m is the <u>slope </u>and b is the <u>y-intercept, </u>or the y-value at which the line intersects the y-axis.

Your slope is 1/3, and your y-int. is -3, so substitute those values in:

y=<u>1/3</u>(x) <u>- 3</u>

Frank can build a fence in twice the time it would take Sandy. Working together, they can build it in 7 hours. How long will it take each of them to do it alone?

Answer

If Frank and Sandy can build the fence in 7 hours, they must be building

1

7

of the fence every hour.

Now, let the amount of time it takes Sandy be

x

hours so that Frank takes

2

x

hours. Sandy can build

1

x

of the fence every hour and Frank can build

1

2

x

of the fence every hour.

We now have the following equation to solve.

1

x

+

1

2

x

=

1

2

x

=

x

=

21

2

=

10.50

Thus, Sandy takes

10.50

hours and Frank takes

21

hours.
