Answer:  5.87 feet per second

<u>Step-by-step explanation:</u>

Use the following conversions:

5280 feet = 1 mile, 1 hour = 60 minutes, 1 minute = 60 seconds

\dfrac{4\ miles}{1\ hour}\times \dfrac{5280\ feet}{1\ mile}\times \dfrac{1\ hour}{60\ minutes}\times \dfrac{1\ minute}{60\ seconds}\quad =\dfrac{21,120\ feet}{3600\ seconds}\\\\\\.\qquad \qquad \qquad \qquad \qquad \qquad \qquad \qquad \qquad \qquad \qquad =\dfrac{5.87\ feet}{1\ second}

Write the standard form of the line that passes through the given points. Include your work in your final answer. Type your answ
ZanzabumX [31]

Answer:

y = \frac{2}{3}x+\frac{13}{3}

Step-by-step explanation:

Okay, the first thing to do here is calculate something known as the "slope".

We know two points are  ( 1 , 5 ) and ( − 2 , 3 )

The slope is represented by "m" in the standard form: y = mx+b

The slope is also known as the rise over the run, y2-y1/x2-x1 = \frac{3-5}{-2-1} = \frac{2}{3}

=> the standard form: y = \frac{2}{3}x+b

Now we have to use the slope, and resubstitute another point to get b

5 = \frac{2}{3}(1) + b

<=> b= 5-\frac{2}{3} = \frac{13}{3}

So the equation that model the line is: y = \frac{2}{3}x+\frac{13}{3}
