x-2y=8

-2y=-x+8

y=1/2x-4 (divide by -2 everywhere)

-4 is the y intercept.

A bus travels 6 hours at a constant speed of 36 miles per hour. How far does the bus travel?

Amanda [17]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - <u>a </u><u>bus </u><u>takes </u><u>6</u><u> </u><u>hours</u><u> </u><u>to </u><u>travel </u><u>a </u><u>particular</u><u> </u><u>distance </u><u>with </u><u>a </u><u>constant</u><u> </u><u>speed </u><u>of </u><u>3</u><u>6</u><u> </u><u>km/</u><u>hr</u>

To calculate - <u>the </u><u>total </u><u>distance </u><u>travel </u><u>by </u><u>the </u><u>bus</u>

We know that ,

$\bold{\longrightarrow \: speed = \frac{distance}{time}} \\$

<u>this </u><u>formula</u><u> </u><u>can </u><u>be </u><u>transformed</u><u> to</u><u> </u><u>find</u><u> </u><u>out </u><u>distance</u><u> </u><u>,</u><u> </u><u>as </u><u>follows </u><u>~</u>

$\bold {\: \longrightarrow \: distance = speed \times time}$

now ,

<u>substituting</u><u> </u><u>the </u><u>values </u><u>in </u><u>the </u><u>formula </u><u>state</u><u>d</u><u> </u><u>above </u><u>,</u>

$\bold{\longrightarrow \: distance = 36 \times 6} \\ \\ \bold{\longrightarrow \: distance = 216 \: km}$

thus ,

<u>the </u><u>bus </u><u>travels </u><u>a </u><u>distance</u><u> </u><u>of </u><u>2</u><u>1</u><u>6</u><u> </u><u>km</u><u> </u><u>in </u><u>6</u><u> </u><u>hours</u>
