sorry im really bad at linear equations

fuzzybird · Answer

That's okay.

y = 1/8x + 3.5miles

royalranger · Answer

Would you like me to explain?

fuzzybird · Answer

yes please

royalranger · Answer

Alright. So he went from Boston to CH to Lexington. and they tell us Boston to lexington is 3.5 miles. Then they tell s his horse goes 1/8 of a mile every minute, hence:
|dw:1481848898698:dw|

royalranger · Answer

Then we just add them together and set them equal to y like they ask us to

fuzzybird · Answer

So if I plug that in, I get a graph that looks something like  this.

Am I on the right track here?

fuzzybird · Answer

no wait I'm not I need to solve for Y I think.


I apologize, I think I got mixed up.

fuzzybird · Answer

If I solve for Y, I get y=x/8+3.5

royalranger · Answer

Why would you do that? you are not supposed to find what y is. If you did, you would need a value for x, which you are not given.

fuzzybird · Answer

So wait.. what do I do now?

royalranger · Answer

Thats it. That is the linear equation. y = (1/8)x + 3.5 is the equation of a line.

Thank you!
